tlbuild: freetype library

 
 6.4.3 The 'freetype' library in 'libs/freetype2'
 ------------------------------------------------
 
 This module uses a wrapper build system.  In contrast to the proxy build
 described earlier, the wrapper build has an almost trivial
 'configure.ac' and a 'Makefile.am' which invokes the 'configure' and
 'make' in the distributed source, followed by 'make install' with the TL
 build tree as destination.  In other words, this actually uses the build
 system provided by upstream (possibly patched).
 
    The flags required for the system library are obtained through
 'freetype-config'.
