By default, Lagrange should have ENABLE_FRIBIDI and ENABLE_HARFBUZZ be
ON, whereas ENABLE_FRIBIDI_BUILD and ENABLE_HARFBUZZ_MINIMAL are set
OFF, just as the script states.  It would seem to be a bug elsewhere
then.

Try to check the build log to see whether or not harfbuzz and fribidi
respectively get correctly detected by CMake.  It ought to use pkg-
config to do so, but I don't trust CMake on a fundamental level.  If it
does, there might be a problem with how Lagrange uses them?
