Personally I've never tried to build a 64-bit app/lib on a 32-bit machine, only the other way around. Looking at the packages available for my favourite Linux distribution (ArchLinux) there doesn't seem to be a compiler that could go the way you want. It should be possible though, you just need to get your hands on a compiler: http://stackoverflow.com/questions/7582218/gcc-compile-a-64-bit-binary-on-32-bit-platform So, the easiest way in CMake would be to create different folders and then generate makefiles/ninjafiles/whatever with different CFLAGS settings. /M -- 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.
