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.
I'm not really happy about this to be honest, I don't like having both
-- and -D options, I think it's stupid to have two ways to do exactly
the same thing, especially since we then have to validate that someone
hasn't passed the argument both ways.
However, other people want this, so here it is.
Fixes#969
Currently meson only accepts `-Dopt=value` for builtin options when
calling `meson configure` and `--opt=value` for builtin options when
calling `meson` initially. This is a confusing behavior, and users only
get a small warning at the top of a potentially long configuration
summary to catch this.
This has confused end users and developers alike, there are at least 5
duplicates of the bug this fixes, and I have personally been asked about
this more times than I can count. The help documentation doesn't make
it clear that -D cannot be used to set options like prefix and bindir.
This adds support for -D options to the initial meson call, but not --
options to the meson configure call. I think it's better to have one way
to do things, and -- options are kinda one off while -D is used
everywhere else, so lets stick with that.

Previously pkg-config files generated by the pkgconfig modules for static libraries
with dependencies could only be used in a dependencies with `static: true`.
This was caused by the dependencies only appearing in Libs.private even
if they are needed in the default linking mode. But a user of a
dependency should not have to know if the default linking mode is static
or dynamic; A dependency('somelib') call should always pull in all
needed pieces into the build.
Now for meson build static libraries passed via `libraries` to the generate
method automatically promote dependencies to public.
The development version of `glib` (2.55.2) has acquired support for
generating gdbus header and source code files separately. This
allows dependencies to be more fine grained on those targets
depending only on the header.
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.
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.
