This is the VS-specific part of the previous commit; the Visual Studio
backend was ignoring dependencies, add an AdditionalInputs element
similar to what add_custom_build does.
If find_program() returns a file from the source directory, anything
that uses it should add the file to the dependencies, so that they are
rebuilt whenever the script changes. Generator is not doing that.
While at it, I am doing two related fixes:
- Generator is not checking whther the generator actually was found,
resulting in a Python error involving NoneType if it isn't. To minimize
backwards compatibility issues, I am only raising the error when
g.process() is acutally called.
- the error message for custom_target with a nonexisting program
erroneously mention a not-found external program "nonexistingprogram".
The new error is similar to the one I am adding for generators.
If the detected gpgme version is recent enough to match the version in
which upstream pkg-config files were added, assert that the default
found dependency is of the pkgconfig type.
Since gpgme 1.13.0, pkg-config files are available and this is the
preferred way to detect the dependency. Without this, projects that wish
to generate pkg-config files that Requires.private on gpgme, now have
their custom dependency() fallbacks overridden with an incorrect
configtool dependency.
As a newcomer to the Meson build system, I found the documentation of the `library()` function to be a bit misleading. Eventually I found what 'user option' referred to after digging through the docs.
This just adds a link back to the page that describes the options that are referred to in this paragraph.
When using clang as an objc/objc++ compiler, identify if it's a Windows
targeted compiler, so that GnuLikeCompiler::get_pic_args() doesn't use
'-fPIC', which clang considers an error for the Window target.
Future work: Factor out parsing the clang target string from the
detectors for various languages.
Now we have some information in CI logs about what compiler is actually
being used, fix some places where an unexpected compiler is being picked
up.
Avoid picking up gcc-objc and gfortran from PATH in vs2017 image for VS
test runs.
Use clang for objc/objc++ in MSYS2 clang test runs, rather than picking
up gcc from path.
Also install gfortran for fortran tests on Cygwin.
Warn when someone tries to use append() or prepend() on an env var
which already has an operation set on it. People seem to think that
multiple append/prepend operations stack, but they don't.

we can avoid writing code like:
a = c[0]
b = c[1]
by using:
a, b = c
or
a = c[0]
b = c[1:]
by using:
a, *b = c
This saves just a bit of code and is a teeny bit faster. But mostly
for less code
Currently this is implemented as range(min(len(a), len(b)), an then
indexing into a and b to get what we actually want. Fortunately python
provides a function called zip that just does this.
* mtest: fix TAP with --verbose
TAP needs to process the test stdout even if --verbose is passed.
Capture it to a separate temporary file, and print it at the end
of the test if --verbose was passed.
In the future, we could parse it on the fly and print the result of
each TAP test point in verbose mode.
* Prefer "stderr is stdout" to "=="
The previous commit used "==" in accordance with the preexisting code,
but reviewers preferred using "is" instead. Fix both occurrences.
Instad of having special casing of threads in the backends and
everywehre else, do what we did for openmp, create a real
dependency. Then make use of the fact that dependencies can now have
sub dependencies to add threads.
I'll be using this later, but it seems useful to allow dependencies to
that have special handlers to declare that they depend on other
dependencies. This should allow us to stop treating threads special
internally and just make it a normal dependency.
