Hi Olivier, I think you need to set the global property FIND_LIBRARY_USE_LIB64_PATHS to OFF.
BTW, I disagree with Mathieu that building 32-bit libraries/executables on a 64-bit system is cross-compilation. These binaries can be run without a problem on the host system. So, IMHO, you don't need a toolchain file. The only thing you have to do is instruct gcc/g++ to generate 32-bit objects/binaries, using the -m32 option, and tell CMake to look in lib instead of lib64 by setting the aforementioned property. Hope this helps. Best regards, Marcel Loose.
