Apparently it does a explicit version check for automake, but in such a
way that it needs to be patched on new automake versions. Patch this out
while we await the PR upstream to be merged into master.
See: https://github.com/jstedfast/gmime/pull/180
Requires meson 0.59. The command to update the desktop database was not
executed which could lead to the app not appearing on the apps menu
after install.
Build libstemmer as a shared library. Use current mainline since that
at least supports build system args.
Shared lib patch courtesy of Stefano Rivera <stefanor@debian.org>,
updated to current head.
Some remarks:
* Note that Meson adds a hard dependency on Python 3.
* All dependencies and defines are now listed together.
* Some build files were put in their respective subdirectories, e.g. the Geary
engine library will be built from the Meson file in `src/engine`.
* `--fatal-warnings` is no longer an explicit flag, as Meson provides
`-Dwerror=true` for this.
* An explicit resource file needs to be used. The issue to support this from
Meson itself can be found at https://github.com/mesonbuild/meson/issues/706 .
* The `gnome.yelp()` function parses a LINGUAS file so we no longer need to keep
track of all languages in our build system.
* There are no Debian scripts defined in the meson.build files to keep them
clean, but they can be kept as separate scripts in `build-aux`.
* Left out the `dist` target as there is now `ninja dist`
* `geary-docs` is disabled by default, as valadoc-0.38.3 returns errors.
