If a fallback dependency is not found just return None. The
caller can then raise the exception it already has if
required=True, or just continue on if required=False.
This is done by adding a new compiler method called 'no_warn_args' which
returns the argument(s) required for the compiler to emit no warnings
for that compilation.
This take care of not disabling warnings for C code compiled into the
BuildTarget. Also includes tests for ensuring all this.

In the case the main project set a subproject for a dependency another
subprojects uses, that other subproject should rather use the first
subproject rather that using native dependency.
For example in gst-all we set all GStreamer modules as subprojects
and, gst-plugins-base is set after gstreamer core, and
we want gst-plugins-base to always use GStreamer core from the subproject
and not the possibly avalaible native one.
And remove the InternalDependencyHolder class.
In some cases we need to know the type of dependency we are
dealing with. For example in GStreamer if the dependency
is not an internal one, then we need to get some env var
from pkg-config to know where to find some plugins necessary
to run some tests.
This commit adds a 'dependencies' keyword to the
gnome.compile_resources() function, which allows your resource blob
to depend on files generated at build-time from custom_target() or
configure_file() targets.
My current use case for this is source data that gets processed with Gettext
translation tools before being compiled into the resource blob.
This feature only works with GLib version 2.48.2 and above. So the
compile_resources() function now detects GLib version and raises an
error if the version of GLib being used is too old.
The compile_resources() test case is now split into two, so that the
existing one can continue to run on systems with old GLib versions (such
as Ubuntu Xenial, which the automated tests on travisci.org use), but
where new enough GLib is available we also test generating gresource
content.
The existing warning about glib-compile-resources is now only printed
if GLib version is older than 2.50.0 because
<https://bugzilla.gnome.org/show_bug.cgi?id=745754> is fixed in the
2.50.0 release.
Reduces duplicated code, and also use universal_newlines=True which
avoids having to decode the bytes output to string.
We mostly need this so we can pass the *current* process environment to
pkg-config which might've changed since the module was imported. Without
this, subprocess.Popen invokes pkg-config with a stale environment (used
in the unittest added later)
Sometimes people want the library to start with 'lib' everywhere, which
is achieved by setting name_prefix to '' and the target name to
'libfoo'. In that case, try to get the pkg-config '-lfoo' arg right.
Also, don't warn about anything on Windows

There is no reason to not always do this. Without this, we end up with
a relative path to meson.py in build.ninja files when meson.py is
launched using subprocess.Popen and friends from the meson source root.
This was causing the unittests to intermittently fail when regen was
getting invoked by the pic test. Funnily enough, this only happened when
run via ./run_tests.py because __file__ was 'run_unittests.py' in that
(as opposed to './run_unittests.py') case which made
os.path.dirname(__file__) be '', and the os.path.split test in meson.py
thought that meson.py was invoked via PATH.
In Fedora we don't care about prefix, we want to ensure that libdir
is /usr/lib64, localedir is /usr/share/locale, and cetera.
Additionally, we don't need to ensure that prefix is absolute as we
check it in main.
Fixes: cc19bf0f45 ("Move option validation in objects rather than doing it only in the conf script.")
