In libraries.m4 LIB_SETUP_FREETYPE we setup freetype handling. Getting freetype correct is a constant source of problem, mostly because freetype (and the boot-jdk) is typically the one thing that can't be automatically detected and must be provided by the user. Therefore this needs special attention.

On Windows, this is even more of a mess. There is no official freetype windows build. There is however, a commonly downloaded binary, from GnuWin32 (which is also the one we officially recommends).

If freetype is missing on Windows x86, we should display this help:
---
To install freetype, run:
wget "http://gnuwin32.sourceforge.net/downlinks/freetype.php" -O /tmp/freetype-setup.exe
chmod +x /tmp/freetype-setup.exe
/tmp/freetype-setup.exe
Follow GUI prompts, and install to default directory "C:\Program Files (x86)\GnuWin32".

Note that this is for x86 (32-bit) only. For x86_64, there is no easily available prebuild binary, and a recompile from source is needed.

If freetype is missing on Windows x86_64, we should display this help:

You need to build a 64-bit version of freetype.
This is not readily available.
