When building a Rust target with Rust library dependencies, an
`--extern` argument is now specified to avoid ambiguity between the
dependency library, and any crates of the same name in `rustc`'s
private sysroot.
Includes an illustrative test case.
The documentation doesn't require it and the interpreter code works around the
possibility of it being None. The ninja backend code however fails with
File "/home/whot/code/meson/mesonbuild/backend/ninjabackend.py", line 796, in generate_data_install
dstabs = os.path.join(subdir or None, plain_f)
File "/usr/lib64/python3.6/posixpath.py", line 78, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
If install_dir is missing, default to datadir/projectname
There's no reason not to also look in these places on Cygwin or OSX. Don't
do this on Windows, as these paths aren't meaningful there.
Move test_cross_file_system_paths from LinuxlikeTests to AllPlatformTests.
As written in PR #2856, this code isn't quite right.
An ArgumentNode object can evaluate as False (if it's arguments attribute is
an empty sequence).
If that happens, we then try to hand the location kwarg down to print(),
rather than removing it, which causes an invalid keyword argument exception.
This failure can be seen e.g. when generating for gnome-twitch (See [1])

Unusually, the cygwin package for openmpi installs headers into
/usr/include, rather than /usr/include/openmpi
Prevent pkg-config from suppressing that -I flag, so a gfortran INCLUDE can
find those files
Also don't resolve -lfoo args only when libpaths are defined.
cc.find_library() also searches in the toolchain directories, and the
static library might be there.
Older versions of GDC had broken support for the -MQ flag (resulting in
a compiler error). New versions of GDC have this issue fixed (some older
versions received a backport). Starting with GCC 7.1 we can assume
dependency generation to always work reliably.
A hard error makes this feature useless in most cases since a static
library usually won't be found for every library, particularly system
libraries like -lm. Instead, warn so the user can provide the static
library if they wish.
This feature will be expanded and made more extensible and more usable
in the future.
