A current rather untyped storage of options is one of the things that
contributes to the options code being so complex. This takes a small
step in synching down by storing the compiler options in dicts per
language.
Future work might be replacing the langauge strings with an enum, and
defaultdict with a custom struct, just like `PerMachine` and
`MachineChoice`.
This does a couple of nice things, one is that editors like vscode can
be configured to use this schema to provide auto completion and error
highlighting if invalid values are added or required values are missing.
It also allows us test that the format of the test matrix work in a unit
test, which I've added. It does require that the python jsonschema
package is installed.
I have an NVME drive, I really don't want to be thrashing it with
temporary files. It's also annoying to watch vscode thrash about with
files that are quickly created and deleted. I'd rather put them in /tmp,
so I've added a non-default option to do so.
By building the generator for the build machine always, and only for the
host machine if an exe_wrapper is available. This makes sense to me as
generally you are going to build the generator for the build machine,
not the host machine, but testing on the host machine makes sense too.
When taking library dependencies from CMake, we first attempt to look
the dependency up in the target list, then fall back to treating it as a
path, which we add if the path exists.
As there is no check for whether or not the path is really a path, this
can cause false positives; for example if a 'uuid' dependency was passed
intending to be a target, but it cannot be found and the current
directory also contains a file or directory named 'uuid', we will just
include the string 'uuid' in library dependencies.
This is particularly prevalent on Windows, where a system library called
'version' exists, and thanks to case insensitivity will match a file
called 'VERSION' if found in the source root when running Meson from the
source directory, or a generated file when running Meson from the build
directory.
Fix this check to only look up filesystem existence on absolute paths,
not unqualified.
This also adds a fallback warning in case an argument cannot be found,
rather than silently falling back.
On Windows, library dependencies can be passed with no prefix or suffix;
rather than -lfoo or foo.dll, they can just be passed as 'foo'.
CMake handles this and suffixes the library with '.lib' or '.dll',
depending on the link mode.
Do the same here, and if we've been passed an unqualified non-option
bare name on Windows, add the appropriate suffix and pass it through to
the linker. This fixes dependencies on system libraries.
When finding dependencies from CMake, use a smarter regex to determine
whether or not a dependency is actually a link argument, and pass
through Windows link arguments properly.
Currently, looking for a nonexisting program using find_program() will
return an NonExistingExternalProgram instace with the default name
'nonexistingprogram'. Let's store the target program's name in it, so it
can be printed if needed.

Currently, the error message is printing the object itself. Showing the
program's name is better.

It can happen that a server is temporaly down, tarballs often have
many mirrors available so we should be able to add at least one fallback
mirror in wrap files.
Refine documentation of the default name_prefix, so people don't get the
impression they can write logic which uses 'lib' as the default, when
they should be defaulting to '[]', to let us take care of the
complexities.
Adjust the handling of a name_prefix: [] kwarg to be the same as
name_suffix: [] kwarg, i.e. identically to the case where it's omitted,
so BuildTarget.prefix doesn't get set (so the default is used).
Also clarify the error reported when a non-empty list is used.
