That will also fix it for using CMake 3.7. Buildroot does not have any problems with searching for libraries in lib32. It does have a problem with having a host rpath used for linking with libraries. So, turning of the search for lib32 is really just a workaround to get rid of the host rpath. From my understanding, there are some possibilities to fix this issue: 1) Prefer to search in lib if FIND_LIBRARY_USE_LIB32_PATHS is enabled, and only search in lib32 in case the target is not found in lib. 2) Make sure, in case lib32 is a symlink, to follow the symlink. 3) Make sure, in case lib32 is a symlink to lib and is not included in the linker search paths, to add it to the implicit runtime search paths.
