This simplifies a lot of code, and centralize "key=value" parsing in a
single place.
Unknown command line options becomes an hard error instead of
merely printing warning message. It has been warning it would become an
hard error for a while now. This has exceptions though, any
unknown option starting with "<lang>_" or "b_" are ignored because they
depend on which languages gets added and which compiler gets selected.
Also any option for unknown subproject are ignored because they depend
on which subproject actually gets built.
Also write more command line parsing tests. "19 bad command line
options" is removed because bad cmd line option became hard error and
it's covered with new tests in "30 command line".
All options are now the projectoptions list, regardless of how they got
defined in the command line.
This also delays setting builtin option values until the main project()
default options are parsed to simplify the code. This is possible
because we already delayed setting the backend after parsing main
project() in a previous commit.
The project() function could have a different value for the backend
option in its default_options kwargs.
Also set backend options, passing them in command line had no effect
previously.
This makes it possible to customize permissions of all installable
targets, such as executable(), libraries, man pages, header files and
custom or generated targets.
This is useful, for instance, to install setuid/setgid binaries, which
was hard to accomplish without access to this attribute.
This checks not only for existence, but also for usability of the
header, which means it does a full compilation and not just
pre-processing or __has_include.

This will copy the file to the build directory without trying to read
it or substitute values into it.
Also do this optimization if the configuration_data() object passed to
the `configuration:` kwarg is empty, and print a warning about it.

For now dicts are immutable, and do not expose any methods,
they however support "native" syntax such as [] lookup,
and foreach iterating, and can be printed.
The fallback might be not used not only because it couldn't be found, but
also because something went wrong trying to use it.
Also, update a test which relies on the specific text
It seems that some projects relied on the previously buggy
behaviour of accepting a 2-element list as the single argument
to configuration_data.set().
Special-case this behaviour, and emit a deprecation message.
When passing more than one -Dc_args it should override the value
instead of appending. This is how all other options works.
Value should be split on spaces using shlex just like it does with
CFLAGS environment variable.
Fixes#3473.
This commit adds private_headers option in dependency method which tells
QtDependency to add private headers include path to build flags.
Since there is no easy way to do this with pkg-config only qmake method
supports this, so with private_headers set qmake will always be used.

To maintain backward compatibility we cannot add recursive objects by
default. Print a warning when there are recursive objects to be pulled
and the argument is not set. After a while we'll do pull recursive
objects by default.
This adds a new method, partial_dependency to all dependencies. These
sub dependencies are copies of the original dependency, but with one or
more of the attributes replaced with an empty list. This allows creating
a sub dependency that has only cflags or drops link_arguments, for
example.
Since we want to make the options passed to `meson` and `meson
configure` equivalent, we need to allows pass -D<lang>_args and
-D<lang>_link_args to `meson`. This path assumes that if one is set then
the other must be, which isn't true.
Otherwise we can't do the following workflow:
if not find_program('foo', required : false).found()
subproject('provides-foo')
endif
Where 'provides-foo' has a meson.override_find_program() on
a configure_file() or similar.
The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
Copy the algorithm used by autoconf.
It computes the upper and lower limits by starting at [-1,1] and
multiply by 2 at each iteration. This is even faster for small numbers
(the common case), for example it finds value 0 in just 2 compilations
where old algorithm would check for 1024, 512, ..., 0.
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:

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.
