CMake can't find freeglut-3.0.0 - windows

Freeglut-3.0.0 is build with cmake (MinGW makefiles) and mingw and then successfully installed with mingw32-make install to C:/Program Files (x86)/freeglut.
My CMakeLists.txt is:
cmake_minimum_required(VERSION 3.7)
project(math_tests)
set(TESTS_SOURCES tests.cpp gl_core_3_3.c)
set(CMAKE_CXX_STANDARD 11)
# GLUT
find_package(GLUT REQUIRED)
include_directories(${GLUT_INCLUDE_DIR})
if(NOT GLUT_FOUND)
message(ERROR "GLUT not found!")
endif(NOT GLUT_FOUND)
# OpenGL
find_package(OpenGL REQUIRED)
include_directories(${OpenGL_INCLUDE_DIRS})
link_directories(${OpenGL_LIBRARY_DIRS})
add_definitions(${OpenGL_DEFINITIONS})
if(NOT OPENGL_FOUND)
message(ERROR "OPENGL not found!")
endif(NOT OPENGL_FOUND)
add_executable(tests ${TESTS_SOURCES})
target_link_libraries(tests math ${GLUT_LIBRARIES} ${OPENGL_LIBRARIES})
Now CMake prints error: Could NOT find GLUT (missing: GLUT_glut_LIBRARY).
I can't figure out what I am doing wrong.

Your CMakeLists.txt file statement
find_package(GLUT REQUIRED)
is going to execute this code from FindGLUT.cmake
find_library( GLUT_glut_LIBRARY NAMES glut glut32 freeglut
PATHS
${OPENGL_LIBRARY_DIR}
${GLUT_ROOT_PATH}/Release
)
and find_library is in your scenario unable to find any of glut glut32 freeglut libraries, because it doesn't know where they are (which for you are under C:/Program Files (x86)/freeglut).
In your case you could set ${OPENGL_LIBRARY_DIR} to the right directory, that is the one containing the freeglut.dll file, for e.g.:
set(OPENGL_LIBRARY_DIR "C:/Program Files (x86)/freeglut/lib")
given the file is under C:/Program Files (x86)/freeglut/lib directory.

How to find Google Test with find_package using CMake on Windows?

I have tried without success to use the find_package function in CMake to make use of a pre-built "system wide" version of GTest in Windows. Here is a minimal, reproducible example of my CMakeLists.txt:
cmake_minimum_required(VERSION 3.2)
find_package(GTest REQUIRED)
if(NOT GTEST_LIBRARY)
message("GTest not found!")
endif()
I try to generate build files using the following command:
cmake .. -G"Visual Studio 14 2015" -DGTEST_ROOT="c:\Libs\googletest"
The c:\Libs\googletest path contains my pre-built GTest (with header files and binaries). I have studied the FindGTest.cmake file in my CMake installation (I use CMake version 3.13.3) and tried all kinds of folder structure, but I always get the following error message:
CMake Error at C:/Program Files/CMake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find GTest (missing: GTEST_LIBRARY GTEST_INCLUDE_DIR
GTEST_MAIN_LIBRARY)
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.13/Modules/FindGTest.cmake:196 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:2 (find_package)
Has anyone succeeded in using find_package for GTest in Windows? If so, how did you do it?
First you must build AND install Googletest using CMake build system
Then try to locate the GTestConfig.cmake file in the installation directory
So now you can add this path to the CMAKE_PREFIX_PATH variable.
Thus configuring your project using CMake, it should be able to find_package(GTest) using the usual search procedure.
So you just have to use GTest::GTest to consume it (i.e. target_link_libraries(.... GTest::GTest) ).
note: For people using FetchContent/add_subdirectory(googletest) beware google/googletest still not provide ALIAS target see https://github.com/google/googletest/issues/2429

Build GL application with CMake, GLEW_DIR and GLFW_DIR not set

I'm trying to build a demo depending on GLEW and GLFW on macOS. I have installed GLEW and GLFW with brew and they both locate under /usr/local/Cellar. Then I use CMake to locate dependencies and my codes are as follows:
# for GLEW
set(GLEW_DIR /usr/local/Cellar/glew/2.1.0/lib/cmake/glew)
find_package(GLEW REQUIRED PATHS ${GLEW_DIR} NO_DEFAULT_PATH)
message(STATUS ${GLEW_INCLUDE_DIR})
# for GLFW
find_package(PkgConfig REQUIRED)
pkg_search_module(GLFW REQUIRED glfw3)
message(STATUS ${GLFW_INCLUDE_DIR})
But as a result the first message always prints /usr/local/include and the second prints nothing. What's the problem with my CMake code? Thanks.

Point FindBoost CMAKE to boost_python Windows 10, VS 2017

My high level goal is to install the BGSlibrary which requires boost for python on Windows 10 using Visual Studio 2017. I compiled opencv and boost (1.64.0) from source using cmake 3.9.0. During cmake for BGSLIBRARY I get
$ cmake -DBGS_PYTHON_SUPPORT=ON -DBOOST_ROOT="C:/Program Files/boost_1_64_0/" ..
-- BGSLIBRARY WITH PYTHON SUPPORT: ON
-- OpenCV library status:
-- version: 3.3.0
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.9/ Modules/FindBoost.cmake:1877 (message):
Unable to find the requested Boost libraries.
Boost version: 1.64.0
Boost include path: C:/Program Files/boost_1_64_0

No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the

Boost.

I've seen lots of questions on the cmake findboost module. Okay lets start from here.
I downloaded and extract boost 1.64.0 and placed it here
I ran bootstrap.bat and .b2 to generate the build boost
C:\Program Files\boost_1_64_0>b2 toolset=msvc-14.1 --with-python --user-config=user-config.jam
with a user config
import toolset : using ;
using msvc : 14.1 ;
using python
: 2.7 # Version
: C:\\Python27\\python.exe # Interpreter
: C:\\Python27\\include # inc dir
: C:\\Python27\\libs # link libs
: # conditions
;
I can see python source here
and can confirm that from within the Visual Studio 2017 command prompt I build boost with python support and it finds all targets successfully.
I can see a bunch of "python" .lib files here. Reading other questions suggests that is where it goes.
But I can't seem to get cmake to see it.
I've tried changing the name libboost_python to boost_python. I've tried pointing in cmake -DBOOST_ROOT, or -DBOOST_LIBRARYDIR (or non-debg, -BOOST_LIBRARYDIR). I've tried adding to the lib dir to PATH. But nothing seems to work. Is this a cmake problem, a incomplete boost installation or a problem with BGSLibrary?
EDIT
To answer #utopia, the CMakeList section in question reads
if(BGS_PYTHON_SUPPORT)
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost REQUIRED COMPONENTS python)
find_package(PythonLibs REQUIRED)
message(STATUS "Boost library status:")
message(STATUS " version: ${Boost_VERSION}")
message(STATUS " libraries: ${Boost_LIBRARIES}")

message(STATUS "Python library status:")
message(STATUS " version: ${PYTHON_VERSION}")
message(STATUS " libraries: ${PYTHON_LIBRARIES}")
message(STATUS " include path: ${PYTHON_INCLUDE_DIRS}")
endif()
Does this mean that the .lib should be literally named python.lib? With no other characters or perhaps boost_python.lib. Is it that specific?
Building Boost.Python
#utopia led me to the right solution. The .lib needs to be literally named boost_python.lib, not appended with the visual studio compiler version, boost version etc. I was able to successfully build after that, no cmake flags needed.

How to properly link boost with cmake

The root directory of boost ($ENV{BOOST_ROOT}) is
C:\Boost\boost_1_64_0
All compiled libraries (.dll, .lib) are in
C:\Boost\boost_1_64_0\lib64-msvc-14.1
They have both boost_xxx and libboost_xxx.
My cmake file is
set(BOOST_ROOT "$ENV{BOOST_ROOT}")
set(BOOST_LIBRARYDIR "$ENV{BOOST_ROOT}/lib64-msvc-14.1")
message("${BOOST_ROOT}")
message("${BOOST_LIBRARYDIR}")
message("${Boost_INCLUDE_DIR}")
if(MSVC)
add_definitions(-DBOOST_ALL_NO_LIB)
add_definitions(-DBOOST_ALL_DYN_LINK)
endif()
find_package(Boost 1.64.0 COMPONENTS system filesystem program_options REQUIRED)
And the output is
C:\Boost\boost_1_64_0
C:\Boost\boost_1_64_0/lib64-msvc-14.1
C:/Boost/boost_1_64_0

CMake Error at CMakeLists.txt:84 (message): Boost not found
Could someone help please? I have spent hours on this but couldn't figure out why this doesn't work.
First of all, what CMake version do you use? Recently a regression fix was included into 3.8.1 release -- it was about backslashes in BOOST_ROOT.
Secondly, you don't need to specify anything else ('cept maybe the BOOST_ROOT) if you are using official prebuilt Windows binaries -- FindBoost.cmake would try to find them as well. (Unfortunately I can't recall since what version.)
Never do set(BOOST_ROOT...) in your CMakeLists.txt -- just pass this parameter to cmake run via -D option. A better way is the following:
if(NOT DEFINED BOOST_ROOT AND NOT "${ENV{BOOST_ROOT}" STREQUAL "")
set(BOOST_ROOT "$ENV{BOOST_ROOT}")
endif()
Use imported targets to link w/ needed Boost libraries and to modify compile/linker flags per taget. Please avoid to modify "global" compiler/linker options -- i.e. use corresponding target_xxx commands instead of add_definitions & etc.
I use the following script to load boost with CMake (working with Linux and Windows) :
set(BoostPath "${DefaultBoostPath}" CACHE PATH "Path to Boost")
message(STATUS "Path to Boost: ${BoostPath}")
set(BOOST_ROOT "${BoostPath}")
set(Boost_USE_MULTITHREAD ON)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_NO_SYSTEM_PATHS ON)
set(Boost_ADDITIONAL_VERSIONS "1.57.0" "1.57" "1.58.0" "1.58" "1.59.0" "1.59" "1.60.0" "1.60" "1.61.0" "1.61" "1.62.0" "1.62" "1.63.0" "1.63" "1.64.0" "1.64")
find_package(Boost ${RequiredBoostVersion} REQUIRED COMPONENTS ${RequiredBoostComponents})
mark_as_advanced(FORCE Boost_DIR)
set(BoostVersion "${Boost_MAJOR_VERSION}.${Boost_MINOR_VERSION}.${Boost_SUBMINOR_VERSION}")
message(STATUS "Boost version: ${BoostVersion}")
if(CompilerName STREQUAL "gcc")
set(System_LIBRARIES ${System_LIBRARIES} pthread rt)
endif()
You can see I have to add some versions of Boost because my version of CMake doesn't know last versions.
What's your CMake version ? Maybe it's the same problem.
Where are your headers? I don't think it found the include directory (which is necessary for this to be successful).
Search for FindBoost.cmake in your cmake installation directory, there are lots of useful things in there for troubleshooting.
using set(Boost_DEBUG ON) can help you figure out which paths are searched and what the filenames of the libraries are searched. You can specify the include directory (directory where folder boost is stored) with set(Boost_INCLUDEDIRS ${BOOST_ROOT}/inc), though what I just showed is one of the places that FindBoost.cmake searches.
Also, you don't need set(BOOST_ROOT "$ENV{BOOST_ROOT}"). FindBoost.cmake does that for you if you don't set ${BOOST_ROOT}.
Note that if you just downloaded boost, extracted the archive to ${BOOST_ROOT} and compiled with b2, then all of your files are in ${BOOST_ROOT}/stage. This is also a good place for them to reside. If you manually copy files somewhere else, then FindBoost may have some troubles finding them.

CMAKE: how to include and link alternative libraries?

My project need four libraries including MPI, BOOST, VTK and SQLITE3. Since BOOST and SQLITE3 are too old, I installed new version of the two libraries and the old version are not uninstalled:
BOOST # alternative BOOST
|___include
|___lib
|
SQLITE # alternative SQLITE
|___bin
|___include
|___lib
|___share
|
Mypoject
|___src
| |___CMakeLists
| |___.cpp and .h file
|
|___CMakeLists
And I used FindSQLite3.cmake to find the alternative SQLite3:
# Look for the header file.
FIND_PATH(SQLITE3_INCLUDE_DIR sqlite3.h /export/home/hh/hh/sqlite/include)
# Look for the library.
FIND_LIBRARY(SQLITE3_LIBRARY sqlite3 /export/home/hh/hh/sqlite/lib)
# Handle the QUIETLY and REQUIRED arguments and set SQLITE3_FOUND to TRUE if all listed variables are TRUE.
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(SQLITE3 DEFAULT_MSG SQLITE3_LIBRARY SQLITE3_INCLUDE_DIR)
# Copy the results to the output variables.
IF(SQLITE3_FOUND)
SET(SQLITE3_LIBRARIES ${SQLITE3_LIBRARY})
SET(SQLITE3_INCLUDE_DIRS ${SQLITE3_INCLUDE_DIR})
ELSE(SQLITE3_FOUND)
SET(SQLITE3_LIBRARIES)
SET(SQLITE3_INCLUDE_DIRS)
ENDIF(SQLITE3_FOUND)
MARK_AS_ADVANCED(SQLITE3_INCLUDE_DIRS SQLITE3_LIBRARIES)
I am trying to link alternative libraries by following lines:
# CMake version

CMake could not find the alternative SQLite3, and could find the old version:
-- /usr/include
-- /usr/lib64/libsqlite3.so
but the new version is located at:
/export/home/hh/hh/sqlite/include
/export/home/hh/hh/sqlite/lib/libsqlite3.so
I am very new to CMAKE, please help me, thank you in advance!
I will explain this using boost as an example. This is how I have it done in my setup.
Let's assume the newer boost version is installed in:
/export/home/hh/hh/Boost/boost-1_60/boost/include/
/export/home/hh/hh/Boost/lib
Now in CMakeLists.txt add these paths to CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH:
LIST (APPEND CMAKE_INCLUDE_PATH "/export/home/hh/hh/Boost/boost-1_60")
LIST (APPEND CMAKE_LIBRARY_PATH "/export/home/hh/hh/Boost/lib)
Then call FindPackage mentioning the minimum required version and optionally the required library components which are built into .so:
FIND_PACKAGE (Boost 1.60 COMPONENTS "program_options" "log" "system" "filesystem" "thread" "python" REQUIRED)
This should work similarly for other libraries too.
Update:
Add to CMakeLists.txt paths to your custom cmake modules, for example the path where FindSQLite3.cmake is located:
LIST (APPEND CMAKE_MODULE_PATH "${MAINFOLDER}/tools/share/cmake")
Then call: FIND_PACKAGE(SQLite3 REQUIRED)
Also remove: /export/home/hh/hh/sqlite/include and /export/home/hh/hh/sqlite/lib from FindSQLite3.cmake but have them added in a similar to boost way.
Instead of hardcoding these settings in the CMakeLists.txt you should change appropriate value in the cache (builddir/CMakeCache.txt). You can do this
manually
with cmake -D VARNAME=value .
with cmake GUI app
