This is a follow-on to #1936.
@minrk: Would you mind confirming this addresses the original issue (in a homebrew setup with no pkgconfig installed)?
Use freetype-config if pkg-config is not installed
Yup, this builds just fine with freetype from homebrew and no pkgconfig, where master will fail with freetype/config/ftheader.h not found.
freetype/config/ftheader.h not found
Thanks for the verification. Merging.
