Instead, assume the GCC (cross-)compiler toolchain will have the "--enable-multiarch" enabled and the toolchain has a triplet matching the CMAKE_LIBRARY_ARCHITECTURE_REGEX which is set to "[a-z0-9_]+(-[a-z0-9_]+)?-linux-gnu[a-z0-9_]*" as of this writing. If so, CMake will automatically initialize the CMAKE_LIBRARY_ARCHITECTURE with a right value and CMake will use it when searching for libraries, not requiring the build script to spell out the extra path suffixes manually.
