The page I linked says /openmp is a compiler flag (not linker flag), so adding 
it to CMAKE_CXX_FLAGS instead of LINK_FLAGS makes perfect sense.

Ho yes, my bad, however there is still the same issue with forward slashes

I receive the flag with FindOpenMP module. It's sad we can't do :
target_link_libraries(... ${OpenMP_CXX_FLAGS}) for a few target

In the end I add the flags for the whole project :
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")

Re: [CMake] issue with target_link_libraries and MSVC

2016-04-12 Thread Kristian 
I'm not sure, but I think, you should consider 'set_target_properties'
(https://cmake.org/cmake/help/v3.0/command/set_target_properties.html).

E.g.

target_link_libraries(my_target source1.cpp source2.cpp)
set_target_properties(my_target PROPERTIES LINK_FLAGS "\openmp")
