This means that when either cflags or libs lookup fails, this will be
logged always in the log, leading to much easier to debug messages
like:
Called `/usr/local/bin/pkg-config --cflags gnutls` -> 1
pkg-config error with 'gnutls': Could not generate cargs for gnutls:
Package nettle was not found in the pkg-config search path.
Perhaps you should add the directory containing `nettle.pc'
to the PKG_CONFIG_PATH environment variable
Package 'nettle', required by 'gnutls', not found
Run-time dependency gnutls found: NO (tried pkgconfig)
Previously even when meson failed to obtain cflags or libs for a
dependency it would lead to the dependency being found, causing very
confusing errors at build time.
Under Windows, the colon ':' is used after the drive letter.
So, the colon should not be used as a list separator or for splitting,
otherwise it could lead to paths in CMAKE_PREFIX_PATH with a
semicolon ';' between the drive letter and the rest of the path, e.g:
-DCMAKE_PREFIX_PATH=C;/foo/bar
instead of
-DCMAKE_PREFIX_PATH=C:/foo/bar
Use os.pathsep instead of ':' to split the environmental variable
CMAKE_PREFIX_PATH
Most apple system frameworks do not have a Versions directory in them at
all.

There are two variables that CMake takes into account during
find_package() in cross-compiled environments, which are: CMAKE_SYSROOT
and CMAKE_FIND_ROOT_PATH. Those are used in cmFindCommon::RerootPaths()
function, which blindly prepends all search paths with those specified
via CMAKE_SYSROOT and CMAKE_FIND_ROOT_PATH.
Extend search paths by using CMAKE_SYSROOT and CMAKE_FIND_ROOT_PATH in a
similar way as CMake does, so we successfully find CMake packages
information in cross-compiled environments.
In some cases it may be necessary to set PKG_CONFIG_SYSROOT_DIR, like
when you've mounted a host architecture system in an arbitrary path.
Meson will now check the cross files for a [properties]:sys_root
variable and set the PKG_CONFIG_SYSROOT_DIR environment variable based
on that variable.

In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.
this is better, but it's still not perfect. cmake doesn't return quotes
to us in the trace output, and being 100% the same as cmake is pretty
much impossible without that information. What I've done should be a
"good enough" implementation without having to maintain a copy of every
property allowed in cmake, as well as custom properties.
Meson itself *almost* only cares about the build and host platforms. The
exception is it takes a `target_machine` in the cross file and exposes
it to the user; but it doesn't do anything else with it. It's therefore
overkill to put target in `PerMachine` and `MachineChoice`. Instead, we
make a `PerThreeMachine` only for the machine infos.
Additionally fix a few other things that were bugging me in the process:
- Get rid of `MachineInfos` class. Since `envconfig.py` was created, it
has no methods that couldn't just got on `PerMachine`
- Make `default_missing` and `miss_defaulting` work functionally. That
means we can just locally bind rather than bind as class vars the
"unfrozen" configuration. This helps prevent bugs where one forgets
to freeze a configuration.
