If we aren't cross-building, this distinction isn't very interesting
(Most dependencies didn't bother reporting this. pkgconfig did it
unconditionally, and Qt reported as 'native' or 'cross' depending on
is_cross_build(), i.e. ignoring the native: keyword)
If successful, we should identify the method which was successful
If successful, we should report the version found (if known)
If failing, we should identify the methods we tried
Some dependency detectors which had no reporting now gain it
There's all kinds of complexities, inconsistencies and special cases hidden
in the existing behaviour, e.g.:
- boost reports modules requested, and BOOST_ROOT (if set)
- gtest/gmock report if they are a prebuilt library or header only
- mpi reports the language
- qt reports modules requested, and the config tool used or tried
- configtool reports the config tool used
- llvm reports if missing modules are optional (one per line)
We add some simple hooks to allow the dependency object to expose the
currently reported information into the consolidated reporting
Note that PkgConfigDependency() takes a silent: keyword which is used
internallly to suppress reporting. This behaviour isn't needed in
find_external_dependency().
Give ConfigToolDependency() a finish_init callback, so that tool-specific
initialization can be called from the constructor, rather than after
construction in the factory class.
v2:
finalize -> finish_init for clarity
find_external_dependency() now makes and iterates over a list of callables
which are constructors with bound arguments for the dependency objects we
are going to attempt to make, so we can consolidate reporting on these
attempts and handling failures in that function.
dub dependencies allegedly support method:pkgconfig, but this is meaningless
as it's only ever used when the dub method is explicitly requested.
Possibly cut-and-pasted from elsewhere?
Ninja buffers all commands and prints them only after they are
complete. Because of this, long-running commands such as `cargo
build` show no output at all and it's impossible to know if the
command is merely taking too long or is stuck somewhere.
To cater to such use-cases, Ninja has a 'pool' with depth 1 called
'console', and all processes in this pool have the following
properties:
1. stdout is connected to the program, so output can be seen in
real-time
2. The output of all other commands is buffered and displayed after
a command in this pool finishes running
3. Commands in this pool are executed serially (normal commands
continue to run in the background)
This feature is available since Ninja v1.5

Meson tries to find the interpreter path through the "py" launcher on Windows in all
cases which breaks if meson is run under MSYS2 and an official CPython is installed as well.
MSYS2 Python doesn't install a py launcher which results in meson finding the system one instead
even though python2/python3 is in PATH.
Always check if the interpreter name is in PATH before falling back to checking the py launcher.
Meson already had code to propagate link dependencies from static
libraries to programs that use those static libraries.
Unfortunately, it was not handling the special cases of 'threads' and
'openmp' dependencies.
