As I already stated earlier, I was recently fixing the buildscripts for freetype, fontconfig and poppler. For all of them I have a patch now which gives them cmake based buildscripts instead of autotools+derivatives and which fixes some errors so that they compile on both compilers.
Of course there is plenty of room for improvement left - freetype and fontconfig should be able to use the system zlib as a dependency (that is disabled for now), fontconfig and poppler have a lot of if(MSVC) parts now and poppler is linking against kdewin32 - which should not be the case - according to Christian. Plus I want to integrate poppler-data into poppler-src - even if that is not the original intention of the author.
It seems there is a lack of communication sometimes - direct as well as indirect (via a blog e.g.).
I hope this improves within the next time.
