This adds support for introspection builds on Windows that is enabled by
the HB_HAVE_INTROSPECTION option, which will also enable HB_HAVE_GOBJECT
(and so HB_HAVE_GLIB) as they are required for introspection.
In order for this to work one must ensure that the Python installation
listed in PYTHON_EXECUTABLE is the same Python release series that was
used to build _giscanner.pyd (the Python module that is used by
g-ir-scanner), with the same architecture. PKG_CONFIG_PATH and PATH
must be set correctly if $(PREFIX)\bin and/or $(PREFIX)\lib\pkgconfig
are not in the standard PATH and PKG_CONFIG_PATH, which is actually
in-line with the *NIX builds.
This adds support to the CMake build files to support building
HarfBuzz-GObject, which is actually a little bit complicated,
as we need to:
-Run glib-mkenums, which is a Python (for newer GLib/GObject) or PERL
(for older, pre 2.53.4, GLib/GObject) script. This matters more for
Visual Studio builds as shebang lines are not supported, so we need to
test-run it with PERL or Python to determine which is the correct
interpretor to use.
-Next, we need to replace strings in the sources that we obtain from
running glib-mkenums. So, the solution here is to use a small utility
CMake script for our purposes here, to maintain maximum compatibility.
-Ensure that things do work in the Visual Studio IDE builds.
Include the fallback sources in the build, and update
src/Makefile.sources so that it can be read by the CMake build files.
Fix a typo in the DirectWrite configure option so that we can properly
enable DirectWrite builds.
Also, when building the utility program, install them as well.
The new unorm2_normalize has been public API since ICU 4.4, while
the old unorm_normalize has been deprecated since ICU 56.
Now, beginning with ICU 60, unorm_normalize will also be annotated
U_DEPRECATED and trigger the compiler -Wdeprecated-declarations warning.
