Subject: Some specific assistance needed for the Unix build process

Hi folks,

I've just created a branch of POV-Ray that makes use of the FreeType 
library:

https://github.com/POV-Ray/povray/tree/experimental/freetype/source/core

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 
`LIBFREETYPE_MISSING`.

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.

Never mind. I've just cobbled together something that I'm surprisingly 
happy with.

So, no need to worry, and we can wait for the next move ?

Good, good !

I still need people to test it on real-life Unix systems.

I built it (now automated for any further update).

Notice: I always disable io restrictions on my local built.

But at least the end of configure seems happy:

Just wondering, what flavour of Linux are you running?

Not sure there is a portable solution for gnu, clang and other compilers.

I /think/ changing it to

     virtual const char* what() const noexcept override;

should do the trick. Can you do a quick test with that?
