I am using cmake (v3.17.3) to build a starter project that uses some boost (1.73) packages. The boost packages are managed with vcpkg (20.02.04-nohash). To date I have had success. Boost packages and statements like
find_package(Boost COMPONENTS filesystem system unit_test_framework REQUIRED)
result in successful builds. However, when I add boost:python, i.e.
find_package(Boost COMPONENTS filesystem system unit_test_framework python REQUIRED)
I receive the following error from cmake:
[cmake] CMake Error at E:/Program Files/CMake/share/cmake-3.17/Modules/FindPackageHandleStandardArgs.cmake:164 (message):
[cmake] Could NOT find Boost (missing: python) (found version "1.73.0")
I can confirm that boost-python:x64-windows package is installed on my machine - in the same way that the other, working boost packages were installed (vcpkg install boost-pkg:x64-windows).
Other information that may be relevant. Windows 10, VSCode 1.46.0.
I'm pretty new to cmake and vcpkg but would really like to get this to work in VSCode so that I can port the project to a different OS.
I am not able to figure out why am I getting this error.

CMake Error at CMakeLists.txt:154 (message):

It says, Unable to find requested boost library. But I have installed boost 1.48.0 and build it using Visual studio console, and have passed BOOST_LIBRARYDIR=D:/Shark/boost_1_48_0/stage/lib and BOOST_ROOT=D:/Shark/boost_1_48_0.
CMake's FindBoost macros look for the libs in various spots based on the compiler your using. Even if you specify BOOST_LIBRARYDIR, you still have to conform to the standards the FindBoost macro expects for filenames ie:
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_COMPILER}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}-${Boost_LIB_VERSION}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_COMPILER}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}-${Boost_LIB_VERSION}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}
${Boost_LIB_PREFIX}boost_${COMPONENT} )
Example filenames matching this template for visual studio 2013 (aka msvc 12)
$BOOST_LIBRARY_DIR/boost_atomic-vc120-mt-1_58.dll
$BOOST_LIBRARY_DIR/boost_atomic-vc120-mt-gd-1_58.dll
You'll note that the mt for multithreaded build and the gd to indicate it's a debug build. FindBoost is fussy and will look for the debug build if your CMake project has a CMAKE_BUILD_TYPE=Debug
Additionally if your building multithreaded you'll need to define:
Boost_USE_MULTITHREADED=ON
If your still having trouble you define: Boost_DEBUG=1 and you'll see a lot of additional output about how and where FindBoost is searching.
I was building the boost library by downloading source file. The problem was it was not creating .dll (only .lib).
I downloaded boost binary and installed it from installer to get those files, and set the path BOOL_LIBRARYDIR=C:/local/boost/lib64-msvc-14.0 and BOOL_ROOT=C:/local/boost to make it done.
I want to build a library called CSWNet on my machine. Cmake can find Boost_INCLUDE_DIR and Boost_LIB_DIR but it cannot find an option called Boost_DIR which is a directory containing a CMake configuration file for Boost. Where is it? Please help, thanks ahead. The error I got is shown below and I installed boost from ubuntu repository and it's installed in /usr/local.
CMake Error at /usr/local/share/cmake-2.8/Modules/FindBoost.cmake:429 (message):

It seems you misunderstood the meaning of Boost_DIR.
Boost_DIR is an environment variable used as a hint by CMake to find the boost installation directory. If this is set to Boost_DIR-NOTFOUND that does not mean that it did not find Boost. Boost_FOUND is used to indicate whether the search was successful:
find_package(Boost REQUIRED thread)
if(Boost_FOUND)
message(STATUS "Success!")
endif()
In case of a successful search, CMake will also print a diagnostic message during the configure phase which looks something like
Boost version: 1.53.0
Found the following Boost libraries:

Hope its not too late to post this.
Passing it in the command line along with cmake command would resovle it
cmake -DCMAKE_CXX_COMPILER=g++ -DCMAKE_INSTALL_PREFIX=dist -DBOOST_DIR="boost installation location"
i try to compile a program with cmake, but I got stock with this error:
Unable to find the requested Boost libraries.

Detected version of Boost is too old. Requested version was 1.37 (or
newer).

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

I installed already the new boost package under /home/dev/boost_1_45_0.
But always when I try to run cmake again I get still the same error.
I also set
export BOOST_ROOT=/home/dev/boost_1_45_0
But when I execute cd ${BOOST_ROOT} I'm in the right folder.
Can anybody help me? Thanks!
Try to delete your build tree, and then run:
cmake -DBOOST_ROOT=/home/dev/boost_1_45_0 path/to/src path/to/build
I'm trying to configure a project using CMake, but it fails to find Boost libraries even though they are in the specified folder. I have specified Boost_INCLUDE_DIR, Boost_LIBRARYDIR and BOOST_ROOT , but I still get an error saying that CMake is not able to find Boost. What could be the reason of such error?
Are you sure you are doing it the correct way? The idea is that CMake sets BOOST_INCLUDE_DIR, BOOST_LIBRARYDIR and BOOST_ROOT automatically. Do something like this in CMakeLists.txt:
FIND_PACKAGE(Boost)
IF (Boost_FOUND)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
ADD_DEFINITIONS( "-DHAS_BOOST" )
ENDIF()
If boost is not installed in a default location and can, thus, not be found by CMake, you can tell CMake where to look for boost like this:
SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/win32libs/boost")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "C:/win32libs/boost/lib")
Of course, those two lines have to be before the FIND_PACKAGE(Boost) in CMakeLists.txt.
There is more help available by reading the FindBoost.cmake file itself. It is located in your 'Modules' directory.
A good start is to set(Boost_DEBUG 1) - this will spit out a good deal of information about where boost is looking, what it's looking for, and may help explain why it can't find it.
It can also help you to figure out if it is picking up on your BOOST_ROOT properly.
FindBoost.cmake also sometimes has problems if the exact version of boost is not listed in the Available Versions variables. You can find more about this by reading FindBoost.cmake.
Lastly, FindBoost.cmake has had some bugs in the past. One thing you might try is to take a newer version of FindBoost.cmake out of the latest version of CMake, and stick it into your project folder alongside CMakeLists.txt - then even if you have an old version of boost, it will use the new version of FindBoost.cmake that is in your project's folder.
Good luck.
For me this error was simply because boost wasn't installed so on ubuntu:
sudo apt install build-essential libboost-system-dev libboost-thread-dev libboost-program-options-dev libboost-test-dev
I struggled with this problem for a while myself. It turned out that cmake was looking for Boost library files using Boost's naming convention, in which the library name is a function of the compiler version used to build it. Our Boost libraries were built using GCC 4.9.1, and that compiler version was in fact present on our system; however, GCC 4.4.7 also happened to be installed. As it happens, cmake's FindBoost.cmake script was auto-detecting the GCC 4.4.7 installation instead of the GCC 4.9.1 one, and thus was looking for Boost library files with "gcc44" in the file names, rather than "gcc49".
The simple fix was to force cmake to assume that GCC 4.9 was present, by setting Boost_COMPILER to "-gcc49" in CMakeLists.txt. With this change, FindBoost.cmake looked for, and found, my Boost library files.
You can also specify the version of Boost that you would like CMake to use by passing -DBOOST_INCLUDEDIR or -DBOOST_ROOT pointing to the location of correct version boost headers
Example:
cmake -DBOOST_ROOT=/opt/latestboost
This will also be useful when multiple boost versions are on the same system.
I also had a similar problem and discovered that the BOOST_INCLUDE_DIR, BOOST_LIBRARYDIR and BOOST_ROOT env variables must hold absolute paths.
HTH!
In my case Boost was not installed. I used below command on Mac and then cmake find_package(Boost) works like a charm
brew install Boost
Please note upper case 'B' in Boost!
If you are building your own boost do not forget to use the --layout=versioned otherwise the search for a particular version of library will fail
For cmake version 3.1.0-rc2 to pick up boost 1.57 specify -D_boost_TEST_VERSIONS=1.57
cmake version 3.1.0-rc2 defaults to boost<=1.56.0 as is seen using -DBoost_DEBUG=ON
cmake -D_boost_TEST_VERSIONS=1.57 -DBoost_DEBUG=ON -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
One more bit of advice for anyone trying to build CGAL in particular, with statically linked Boost. It is not enough to define Boost_USE_STATIC_LIBS; it gets overridden by the time Boost_DEBUG outputs its value. The thing to do here is to check the "Advanced" checkbox and to enable CGAL_Boost_USE_STATIC_LIBS.
I had the same problem while trying to run make for a project after installing Boost version 1.66.0 on Ubuntu Trusty64. The error message was similar to (not exactly like) this one:
CMake Error at
/usr/local/Cellar/cmake/3.3.2/share/cmake/Modules/FindBoost.cmake:1245 (message):

Boost was definitely installed, but CMake couldn't detect it. After spending plenty of time tinkering with paths and environmental variables, I eventually ended up checking cmake itself for options and found the following:
--check-system-vars = Find problems with variable usage in system files
So I ran the following in the directory at issue:
sudo cmake --check-system-vars
which returned:
Also check system files when warning about unused and uninitialized variables.
-- Boost version: 1.66.0

-- Configuring done

-- Build files have been written to: /home/user/myproject
and resolved the issue.
See FindBoost.cmake first. The variables you set are the correct ones but they should be all uppercase.
Make sure the library architecture matches with CMake configuration.
cmake -A x64 ..
I suggest creating a minimal executable which only includes a Boost library to see if it compiles.
#include <iostream>
#include <boost/date_time.hpp>
int main() {
using namespace std;
using namespace boost::gregorian;
date today = day_clock::local_day();
cout << today << endl;
}
find_package(Boost REQUIRED COMPONENTS
date_time
)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})
add_executable(test_boost "test_boost.cpp")
target_link_libraries(test_boost Boost::date_time)
Start debugging by checking Boost_FOUND first.
message(STATUS "Boost_FOUND: ${Boost_FOUND}")
The version should be found even if no libraries are found. (Boost_VERSION)
If Boost_LIBRARY_DIRS becomes non-empty, it should compile.
I had the same problem, and none of the above solutions worked. Actually, the file include/boost/version.hpp could not be read (by the cmake script launched by jenkins).
I had to manually change the permission of the (boost) library (even though jenkins belongs to the group, but that is another problem linked to jenkins that I could not figure out):
chmod o+wx ${BOOST_ROOT} -R # allow reading/execution on the whole library
#chmod g+wx ${BOOST_ROOT} -R # this did not suffice, strangely, but it is another story I guess
This can also happen if CMAKE_FIND_ROOT_PATH is set as different from BOOST_ROOT.
I faced the same issue that in spite of setting BOOST_ROOT, I was getting the error.
But for cross compiling for ARM I was using Toolchain-android.cmake in which I had (for some reason):
set(BOOST_ROOT "/home/.../boost")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} --sysroot=${SYSROOT}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${SYSROOT} -I${SYSROOT}/include/libcxx")
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS}")
set(CMAKE_FIND_ROOT_PATH "${SYSROOT}")
CMAKE_FIND_ROOT_PATH seems to be overriding BOOST_ROOT which was causing the issue.
For those using python3.7 docker image, this solved:
apt install libboost-system-dev libboost-thread-dev
Maybe
brew install boost
will help you.
