The sources in src/hb-ucdn and not included correctly into the NMake
Makefiles, as we need their explicit relative location as we pass all the
sources we used into the introspection scanner. This was not an issue
before as we excluded the UCDN sources in the build when we enabled
introspection (meaning GLib is enabled), but since we default on using
UCDN on all builds unless explicitly disabled, we need to deal with this.
This did not affect builds using UCDN without introspection due to the use
of NMake batch rules.
Fix this by creating a NMake Makefile module on-the-fly with the correct
subdir info, and using that list in there instead.
This adds a set of NMake Makefiles that can be used to build HarfBuzz, from
the standard basic build building the minimal HarfBuzz DLL (consisting
of OpenType, fallback and Uniscribe support only), to a full fledged build
consisting of GLib and FreeType support, as well as building the utilities,
the test programs in src/ and test/api, and HarfBuzz-ICU and
HarfBuzz-GObject, and up to building the introspection files. This means a
flexible build mechanism is supported here, so anything that is supported
for a Windows build (code-wise), should all be supported by this build
system.
As in an earlier commit, the source listings are shared with the autotools
builds with the various Makefile.sources in src/, src/hb-ucdn and util/, and
this set of NMake Makefiles will transform these lists into the form they
want.
In the current form, all the test programs in test/api pass, and this has
been checked successfully with 'make -j8 distcheck'.
