Reading my commit message,
In some environments, i. e. when cross building, include files
are not located in the standard path like
`/usr/includes/freetype2`. Make it possible to provide the
correct path without needing to patch `Makefile`.
I would say that it would not work when cross compiling. I am no expert
though. I would recommend to change the entry in HISTORY and I will ask
on openembedded-devel what they suggest.
Thanks,
Paul
