This mirrors the modules keyword argument that some dependencies (such
as qt and llvm) take. This allows an easier method to determine if
modules are installed.
Some things, like `method[...](...)` or `x: ... = ...` python 3.5
doesn't support, so I made a comment instead with the intention that it
can someday be made into a real annotation.
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.
Now, all source files are ignored that are not part of the
language of the target. This is also what CMake does.
Additionally it is now supported to build source files that
are generated inside the build directory.
When the media file for a specific language doesn't exist we try to symlink
it to the C one. If symlinking fails we need to fall back to copying the C
one like in the non-symlink case.
The fallback code path didn't set the source so this always failed.
Also check if the C fallback exists before trying to symlink/copy, otherwise
we crash if C isn't the first lang we try.
Currently default_options uses "" for the kwarks id, however this
is incorect and it must be "/". Additionally, this error won't be
ignored in the future with "--skip" (this is why the tests were
passing and this wasn't detected earlier).
when we are generating the include directories for a build target, then
we are iterating over all include directories, check if they are . or ..
and if not, generate a compile args object for it. However, the join
calls and the generation of the compile object is quite expensive, if we
cache the results of this, then we can _generate_single_compile from 60%
to roughly 50%.
the problem here is, that get_custom_target_provided_libraries iterated
over all generated sources of a target. In each output we check if this
is a library or not. In projects like EFL we have added a lot of
generated target to many different targets, so the iterating of the
output is rather consistent, with this commit we drop from 19% of the
time spending in get_custom_target_provided_libraries down to 3.51%.
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.
