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.
Fixes https://github.com/mesonbuild/meson/issues/2246
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', ...])
