are we assured freetype is allways in this path.

It might be a nightmare for a developer without sudo to make the lib compile
without. Can we find an option that does not depend on standard paths? we can
have a variable with a default that can be override at build type

[ducky, 2013/08/08 21:35:03]

So I think the proper way to do this is to invoke freetype-config and get the
required c flags. I'm also how sure how standard this is on other Linux distros.
As an alternative, we can build all the libraries from scratch, especially since
gypfiles already exist for freetype, fontconfig, and their dependencies. Only
minimal effort should be required to re-enable the Linux builds. Thoughts?
