Looking at the docs a bit closer, it seems like this is the better solution: set( CMAKE_C_FLAGS_INIT -m32 ) set( CMAKE_CXX_FLAGS_INIT -m32 ) Not sure if you'd agree, but at least I can verify it is working. -- 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.
