Without this, MSVC and MSVC_VERSION won't be set by CMake during
platform detection, and the compiler will be an undefined mixture of
GNU and MSVC. In particular, find_package(opencv) will fail on Windows
when building with MSVC.
This is required to make `-include /path/to/custom/target.hpp`
work. This setup is used by wxWidgets and this PR is
required to use wxWidgets as a CMake subproject.
The `debug` builtin option does not control whether or not the debug
CRT is used. Without this fix, when buildtype=debugoptimized or when
debug=true + b_vscrt=md, we will try to link to the debug libraries
found via cmake while linking with `/release`, which will cause a link
failure.
There is nothing to "warn" about, this is a completely routine
occurence. OTOH, when something is corrupted, we should warn. Keep
the red color and "WARNING:" prefix in that case.
Example output:
$ ninja -C build

Fixup for b4b1a2c5a1.
A warning would be printed for any rule with multiple outputs, for
example:
WARNING: custom_target 'coredump.conf.5' has more than one output! Using the first one.
WARNING: custom_target 'dnssec-trust-anchors.d.5' has more than one output! Using the first one.
WARNING: custom_target 'halt.8' has more than one output! Using the first one.
Fixes https://github.com/systemd/systemd/issues/16461.
'native:' keyword was only added in 0.54. For projects declaring
meson_version >= 0.54, warn, because those projects can and should set
the keyword. For older projects declaring support for older versions,
don't warn and use the default implicitly.
Fixes https://github.com/mesonbuild/meson/issues/6849.
Since -Wl,-rpath= is not the only valid rpath ldflags syntax we
need to try and match all valid rpath ldflags.
In addition we should prevent -Wl,--just-symbols from being used to
set rpath due to inconsistent compiler support.

This extends the 109 generatecode test case to also define a test, so
coverage can really detect something.
This avoid printing long backtrace by default, the user already has the
output of the git command printed for debugging purpose since we don't
redirect stdout/stderr.
Add depfile support to generated targets for Qt >= 5.14.
Move warning into the module init itself, to check if the version is too
old before issuing. Also tweak the wording itself, to advise upgrading
to a suitable version of Qt5 instead of advising to wait for a Qt bug to
be fixed.
I made the mistake of always selecting the debug CRT for compiler
checks on Windows 4 years ago:
https://github.com/mesonbuild/meson/pull/543https://github.com/mesonbuild/meson/pull/614
The idea was to always build the tests with debugging enabled so that
the compiler doesn't optimize the tests away. But we stopped doing
that a while ago, and also the debug CRT has no relation to that.
We should select the CRT in the same way that we do for building
targets: based on the options.
On Windows ARM64, the debug CRT for ARM64 isn't always available, and
the release CRT is available only after installing the runtime
package. Without this, we will always try to pick the debug CRT even
when --buildtype=debugoptimized or release.
Some warnings are out of the user's control, such as the RCC QT bug,
or the GNU windres bug, or our informational warning about
auto-disabling of options when -Db_bitcode is enabled.
Such warnings should not be fatal when --fatal-meson-warnings is
passed because there's no action that the user can take to fix it. The
only purpose it serves is to prevent people who use those features
from using --fatal-meson-warnings.
