Add Meson build project file.
Example usage:
# Configure Meson build in directory `build-meson` to generate
# release binaries comparable to to the ones from the
# autotools/make build system.
meson setup build-meson \
--prefix=/usr/local \
--buildtype=debugoptimized \
--strip \
-Db_ndebug=true
# After configuring the Meson build with the above command,
# compile and install to `/usr/local/`; this includes a pkg-config
# file.
ninja -C build-meson install
# Alternatively, compile and install to `/tmp/aa/usr/local/...`
# for packaging.
DESTDIR=/tmp/aa ninja -C build-meson install
# Generate documentation under `build-meson/docs`.
ninja -C build-meson docs
Library size comparison for stripped `libfreetype.so` generated by
all three build systems:
- Default build (autotools + libtool): 712 KiB
- CMake build (RelWithDebInfo): 712 KiB
- Meson build: 712 KiB
* meson.build: New top-level Meson build file for the library.
* meson_options.txt: New file. It holds user-selectable options for
the build, which can be printed with `meson configure`, and selected
at `meson setup` or `meson --reconfigure` time with
`-D<option>=<value>`.
* scripts/parse_modules_cfg.py: A script invoked by `meson.build` to
parse `modules.cfg` and extract important information out of it
(i.e., the list of modules).
* scripts/process_ftoption_h.py: New script invoked by `meson.build`
to process the original `ftoption.h` file. It enables or disables
configuration macro variables based on the available dependencies.
This is similar to what other build systems are using (i.e., Meson's
`configure_file()` command is not used here).
* scripts/extract_freetype_version.py: New script invoked by
`meson.build` to extract the FreeType version number from
`<freetype/freetype.h>`.
* scripts/extract_libtool_version.py: New script invoked by
`meson.build` to extract the libtool `revision_info` data from
`builds/unix/configure.raw`, and to generate the corresponding
shared library suffix.
* scripts/generate_reference_docs.py: New script invoked by
`meson.build` to generate the FreeType 2 reference documentation
(using the `docwriter` and `mkdocs` packages, which must be already
installed).
