This reverts commit 43341cd3e3, reversing
changes made to ffb4befdd8.
This is causing segfault in Geary.JS.to_string_released() when running
client tests, so reverting until a solution is found.
Commit 43341cd3 basically means we require vala 0.38, which excludes
Debian 9 (stretch), Ubuntu 16.04 (artful) and Fedora 26. Hence bump
minimum versions (and tidy up the list of deps) to reflect this.
* meson.build: Use libunwind and libunwind-generic to avoid having to
search for the platform-specific lib.
* src/meson.build: Set UNW_LOCAL_ONLY define to get the most optimal
unwind impl.
* bindings/meson.build: Declare a dependency for JSC that includes both
the lib, VAPI and appropriate build directory. Update WK dependencies
to reflect the same that their pkg-config files currently do, sort.
* meson.build: Rename top-level JSC deps to make it clear what they are
for.
* src/engine/meson.build: Depend on JSC rather than WK, sort deps.
* desktop/meson.build: Make sure the schema is re-compiled with the
source XML changes.
* meson.build: Make compiling the schema mandatory, since both running
the client locally and unit tests require it. Fix path to compiled
schema so the client can find it.
Since libmessaging-menu has a either a broken pkg_config file or a dumb
VAPI name, we need to detect the library and the VAPI in two steps, then
add them both as dependencies.
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.
