Usually you chekc the value of CMAKE_SIZEOF_VOID_P which will be 8 on 64 bits system and 4 on 32 bits ones. e.g. here is what I use: # Test 32/64 bits if("${CMAKE_SIZEOF_VOID_P}" EQUAL "8") message(STATUS "Target is 64 bits") if (WIN32) set(WINXXBITS Win64) endif(WIN32) else("${CMAKE_SIZEOF_VOID_P}" EQUAL "8") message(STATUS "Target is 32 bits") if (WIN32) set(WINXXBITS Win32) endif(WIN32) endif("${CMAKE_SIZEOF_VOID_P}" EQUAL "8") See: http://www.cmake.org/pipermail/cmake/2011-February/042752.html or cmake --help-variable CMAKE_SIZEOF_VOID_P > > thanks for your help > > Eric > -- > > Powered by www.kitware.com > > Please keep messages on-topic and check the CMake FAQ at: > http://www.cmake.org/Wiki/CMake_FAQ > > Kitware offers various services to support the CMake community.
