Try setting CMAKE_SYSROOT instead of CMAKE_FIND_ROOT_PATH.  The find_*()
functions check CMAKE_SYSROOT first if set, and cmake will also pass
"--sysroot=${CMAKE_SYSROOT}" for you.  With clang, I also set
CMAKE_<lang>_COMPILER_TARGET for each language I need, e.g., C, CXX, and
ASM, but that's probably not necessary with gcc.
