This can be useful to make sure that a project builds when
its fallbacks are used on systems where external dependencies
satisfy the version requirements, or to easily hack on the sources
of a dependency for which a fallback exists.
It is weird and inconsistent to have different pc file depending on
default_library value when using library() or build_target(). We should
skip dependencies only when user explicitly want shared library only.
Move call to print_nested_info down into do_subproject()
So we don't print info about possible subproject promotion unless subproject
failure is due to directory non-existence
And we do do that for subproject('foo'), as well as for dependency(fallback:
['foo', ...])
Sometimes it is needed to run the current compiler with specific options
not to compile a file but rather to obtain additional info. For example,
GCC has several -print-* options to query it about the paths to
different libraries and development files. One use case is to get the
location of development files for GCC plugins, which is not easily
obtainable by other means:
gcc -print-file-name=plugin
For this purpose, it would be convenient if the compiler object returned
by meson.get_compiler(lang) could be used in run_command() directly.
This commit implements it.

Use $project_name:$test_setup namespace scheme for test setups. This
allows one to choose from which (sub)project a test setup is taken from
should there be several sharing the same name. Defaults to the main
project. E.g. "meson test --setup subproj:valgrind".
Change the code to store D properties as plain data. Only convert them
to compiler flags in the backend. This also means we can fully parse D
arguments without needing to know the compiler being used.
This can help future generations avoid mistakes like this:
edb1c66239
To avoid breaking builds, this is currently just an error. After
sufficient time has passed this can hopefully become a hard error,
similarly to the already-existing `permittedKwargs` warnings.
Starting with VS 2017 if the output of any command run by VS contains
the word Error it will interpret that as a fatal error, even if the exit
error code is zero.
This messes up the unit tests on VS 2017, because we sometimes want to
deliberately ignore error messages.
Change "Error" to "Problem" to mitigate this issue until a more
permanent solution is found.
Previously, Meson was showing a subproject being downloaded after later
claiming it doesn't exist.
This patch shows the actual error to clarify why the given subproject
can not be used.
- Pass exclude_files and exclude_directories relative to src_dir,
same as specified by user and documented in public install_subdir().
- Make do_copydir() interface similar to do_copyfile():
install src_dir contents to dst_dir.
- Remove src_prefix/src_dir code, it adds confusion and duplicates arguments.
Use single src_dir parameter instead.
- Make callers specify that src_dir contents should be installed
under dst_dir/basename(src_dir) if necessary.
- Use os.path.relpath() instead of string manipulations on paths.
- Add documentation to do_copydir(): specify types and add usage example.
According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

Examples:
meson.build:2:0: ERROR: Dependency is both required and not-found
meson.build:4: WARNING: Keyword argument "link_with" defined multiple times.
These are already matched by the default compilation-error-regexp-alist in
emacs.
Also:
Don't start 'red' markup until after the \n before an error
Unabsorb full-stop at end of warning with location from mlog.warning()
Update warning_location test
This is important so people can not trick Meson to select a
subproject_dir that is not in the project's source directory.
It also ensures a string is used for the path.
The previous change disallowed any subdirectories for subproject dirs,
and therefore broke a couple of projects making use of that.
This change still prevents people from setting subproject dirs that are
not in the project's source tree, while allowing to specify any path
within the project's directory again.
