I've just created a branch of POV-Ray that makes use of the FreeType
Integration into the Windows build process is complete, but now the Unix
build process (most notably `unix/configure.ac`) has to be updated to
compile against and link with the library as well.
I'm sure given enough time and effort I could hack /something/ together
that would /happen/ to work on /my/ machine (Windows subsystem for
Linux), but I'd feel much more comfortable if someone with a good deal
more Unix build Fu could step up and help with this part of the job.
The task at hand is to make the configure script check the
`--with-libfreetype=DIR` and `--without-libfreetype` options, test
whether a modern enough version of FreeType is availebe (if applicable),
and either set compiler and linker flags accordingly or define
As for the version number I would prefer a test against the release
(e.g. 2.6.1), but a test against either the "libtool number" (e.g.
11.0.5) or the "shared obect number" (e.g. 6.5.0) would probably work as
well (see `VERSIONS.TXT in the freetype `docs` directory), as long as
the test is well-defined and reliable.
The only thing this POV-Ray branch currently does with FreeType is query
the version number from the linked library, but I guess that should be
sufficient to test the build process.
