though I do
add_library(${PROJECT_NAME} SHARED ${SOURCES} ${HEADERS})
include_directories(/usr/local/opt/openssl/include)
link_directories(/usr/local/opt/openssl/lib)
target_link_libraries(${PROJECT_NAME} ssl crypto)
the cmake generated compiler command doesn't have -L/usr/local/opt/openssl/lib and linker is terminated by
ld: library not found for -lssl
the /usr/local/opt/openssl/lib do has the libssl.dylib. Does cmake deliberately avoiding it in favour of Apples's ssl library?

I am fairly new to working with the terminal and I am attempting to use cmake to configure a build for a project that involves public transportation routes. When I attempt to make the build I get the following response in the terminal:
$ cmake ..

-- Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES)
-- Could NOT find OpenMP (missing: OpenMP_C_FOUND OpenMP_CXX_FOUND)

Below is what I believe to be the relevant code from the CMakeLists.txt file:
find_package(OpenMP)
if (OPENMP_FOUND)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()

else()

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -DLOGLEVEL=2")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "${CMAKE_CXX_FLAGS} -g -DLOGLEVEL=3")
I have found some similar questions on this and other websites, but I am still struggling to understand the problem because I have never used cmake before and, as mentioned, I am somewhat new to working with the terminal. I would be extremely grateful for any information on what the error messages are actually telling me, or any suggestions on steps I could take/things I could try to solve the issue. I am working on a Mac, if anyone is wondering.
For the compiler to see OpenMP, you may need to set the following options in your cmake command (for dependencies located in /opt/local):
cmake .. \
-DOpenMP_C_FLAGS=-fopenmp=lomp \
-DOpenMP_CXX_FLAGS=-fopenmp=lomp \
-DOpenMP_C_LIB_NAMES="libomp" \
-DOpenMP_CXX_LIB_NAMES="libomp" \
-DOpenMP_libomp_LIBRARY="/opt/local/lib/libomp.dylib" \
-DOpenMP_CXX_FLAGS="-Xpreprocessor -fopenmp /opt/local/lib/libomp.dylib -I/opt/local/include" \
-DOpenMP_CXX_LIB_NAMES="libomp" \
-DOpenMP_C_FLAGS="-Xpreprocessor -fopenmp /opt/local/lib/libomp.dylib -I/opt/local/include"
The two missing CMakeLists.txt are located in git submodules within src/ To download the submodules, cd to the root phaedle directory and issue the following command:
git submodule update --init --recursive
Edit: this is now fixed in master.
How to disable warnings of GCC compiler both in header and source files?
In main CMakeLisits.txt:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Weffc++ -std=c++11")
...
add_subdirectory(lib)
In lib CMakeLisits.txt:
set(lib_SOURCES
...)
include_directories(${lib_SOURCE_DIR}/include ${lib_BINARY_DIR}/include)
add_library(ilib STATIC ${ilib_EXTRA_CFLAGS} ${ilib_SOURCES})
...
..
I've tried add in lib CMakeLists.txt
include_directories(SYSTEM ${lib_SOURCE_DIR}/include ${lib_BINARY_DIR}/include)
and it helped with headers, but I still have warnings in *.cpp files
Then I tried
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-effc++")
in lib, CMakeLists.txt, and warnings in header appeared again
Don't understand what's happening
CMake version 2.8.12.2
gcc version 4.9.3
How do I convince cmake (within CLion) I have the OpenMP headers available? I am trying to compile this project SCD and I receive the following error
...
[ 15%] Building CXX object tools/selector/CMakeFiles/selector.dir/source/main.cpp.o

^
The CMakeLists.txt includes
SET(CMAKE_CXX_FLAGS_DEBUG "-O0 -g -pg -fopenmp -DPROFILE ")
SET(CMAKE_CXX_FLAGS_RELEASE "-O3 -fopenmp -DNDEBUG")
I think that your problem is not specific to CLion but the tool that is used for the building process (i.e CMake) . As already mentioned in this answer, there is a standard module for testing if the compiler supports OpenMP:
find_package(OpenMP)
if (OPENMP_FOUND)
set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()
I have a library in source code, it builds in .a static library, but i need .dylib. So, i choose Mach-O-Type in "Build Settings" as "Dynamic Library", but get error:

libtool for some reason uses "-static" instead "-dynamic" flag... Compatibility version i've set. What do you think could be wrong?
object files (.o) could be extracted from archive file (.a) and then packed in .dylib with libtool or gcc
I try to build my app with CMake on Mac OS X, I get the following error:
Linking CXX shared library libsml.so
ld: unknown option: -soname
collect2: ld returned 1 exit status
make[2]: *** [libsml.so] Error 1
make[1]: *** [CMakeFiles/sml.dir/all] Error 2
make: *** [all] Error 2
This is strange, as Mac has .dylib extension instead of .so.

Build process:
cmake -D BuildType=Debug -D LibraryType=shared .
make
I found, that incorrect command generate in CMakeFiles/sml.dir/link.txt. But why, as the goal of CMake is cross-platforming..
How to fix it?
I had a similar issue on OS X which I resolved using the the install_name switch instead of soname.
gcc -shared <files> -lc -Wl,-install_name,<libname>.so, -o <libname>.so.1
You cleared you're problem, but I wanted to provide this a s a reference for future visitors because there's a bit more to creating a dynamic library on OS X. Also see Creating Dynamic Libraries in the Apple Developer pages.
OS X does not use the convention libcoolstuff.so.X.Y.Z. OS X uses the convention libcoolstuff.X.dylib. The, to embed X.Y.Z into the library, use -install_name, -current_version and -compatibility_version.
I don't know Cmake, but here's how it looks under Make. Your recipe to build the libcoolstuff 1.0.6 will look like:
libcoolstuff libcoolstuff.dylib:
$(CC) $(CFLAGS) -dynamiclib -install_name "libcoolstuff.1.dylib" \
-current_version 1.0.6 -compatibility_version 1.0 -o libcoolstuff.1.dylib $(OBJS)
And your make install rule would look like:
PREFIX?=/usr/local
LIBDIR?=$(PREFIX)/lib
...
install:
cp -f libcoolstuff.1.dylib $(LIBDIR)/libcoolstuff.1.dylib
rm -f $(LIBDIR)/libcoolstuff.dylib
ln -s $(LIBDIR)/libcoolstuff.1.dylib $(LIBDIR)/libcoolstuff.dylib
install_name_tool -change "libcoolstuff.1.dylib" "$(LIBDIR)/libcoolstuff.1.dylib" $(LIBDIR)/libcoolstuff.1.dylib
Under otool, it looks like:
$ otool -L libcoolstuff.dylib
libcoolstuff.dylib:
libcoolstuff.1.dylib (compatibility version 1.0.0, current version 1.0.6)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.7)
Finally, you would use it as expected:
export CFLAGS="-NDEBUG -g2 -O2 -Wall -arch ppc -arch ppc64"
make
...
OK, I found where problem was. Before build, you have to remove all CMake temp folders and files, e.g. CMakeFiles, CMakeCache.txt, Makefile. As in my case, issue was that I built that project on Linux and didn't delete these files...
That's why there's .so extension...
Had a problem with this myself. What fixed it for me was removing the commas and replacing -soname with -install_name
