This fixes the following warning during GIR generation:
> cc1: warning: -Wformat-security ignored without -Wformat [-Wformat-security]
And anyway it is useless to set -Wformat-security if -Wformat is not set
as well, so if we want one, let's have both.
More of the files were wrong, or at least not absolutely identical to
the files generated by the autotools. I am not doing any code change
other than trying to make both build systems produce identical files
(except for slight differences on 2 files not worth the effort) even
though maybe some things can be improved (especially on the include
list). Maybe to be improved later.
Also fixing 2 of the previously autotools-generated files because of
space typos which should have been committed earlier.
Finally it is to be noted that there is no logics to copy the generated
files back to the source directory in the meson rules. I am not sure
anyway this is really worth it and maybe we should just stop tracking
these generated files eventually.
Noticed by Massimo.
gimp_type_set_translation_domain() calls were missing.
Also make so that the output is exactly similar (even whitespaces) as
the autotools one, making it easier to diff, hence maintain.
It should be clear that the autotools build is still the officially
mandated one for all finale builds (i.e. packaging). Our meson builds
still have bugs (some we know of and are trying to fix, others that we
will probably discover soon) so packagers should be well aware that they
should not use meson (though we highly encourage it for developers so
that bugs can be found).
Adding this warning as someone was asking on a bug report whether
autotools were still being supported (while it's the opposite: meson is
still not officially stable and autotools is still our main build
system).
We want to be able to install icons only in a quick command when
testing/developing.
Also I realize that Legacy icons are not even installed with meson
build, which is bad! Even though legacy, we want to keep them (at least
for the time being), just as we do with autotools.
It must not be a boolean but a `feature` option, with `auto` by default.
`auto` value mean enabled for macOS and Win32, and disabled for other
cases. This default logics disappeared in the meson build.
Also the mypaint-brushes package is a mandatory dependency, which must
always be checked. Absence is fatale.
Finally properly set the MYPAINT_BRUSHES_DIR macro depending on the
proper relocatable case.
For pango and libbacktrace, we only need a compilation/link test. No run
is needed.
As for the exchndl (Windows only), this is an optional feature, hence
should not be a fatale check.
3 cases are possible:
- in native build, the test must succeed and is a fatale error.
- in cross-compilation, if no `exe_wrapper` binaries were set in the
toolchain file, we just bypass the check, yet still output a warning
so that packagers won't forget to add the dependency.
- in cross-compilation with an `exe_wrapper` (for instance `wine` for a
win32 target), we run the check. Even if it fails, we don't make it a
fatale error then simply output a warning as cross-platform execution
are not always reliable anyway.
