When cross compiling, users can set CMAKE_FIND_ROOT_PATH to
the sysroot of the TARGET system which adds the sysroot prefix to the
paths used in the FIND_XXX commands. Since these FIND_PATH commands
use absolute paths found on the HOST system, pass
NO_CMAKE_FIND_ROOT_PATH to keep the prefix from being added.
