Replace several checks against GCC_MINGW or (GCC_MINGW, GCC_CYGWIN) with
is_windows_compiler instead, so that clang and other gcc-like compilers
using MinGW work appropriately with vs_module_defs, c_winlibs, and
cpp_winlibs.
Fixes#4434.
It is a common idiom to look for a function or a specific type or
a header in various locations/libraries, and it can be confusing to
see the (seemingly) identical compiler check being done multiple
times.
Now we print the dependencies being used when a compiler check is run
Before:
Checking for function "fbGetDisplay": NO
Checking for type "GLeglImageOES": YES
Checking for function "asinh": YES
After:
Checking for function "fbGetDisplay" with dependency egl: NO
Checking for type "GLeglImageOES" with dependencies glesv2, gl: YES
Checking for function "asinh" with dependency -lm: YES
If a subproject is not required and fails during its configuration, the
parent project continues, but should not include any target or state set
by the failed subproject. This fix ninja still trying to build targets
generated by subprojects before they fail in their configuration.
The 'build' object is now per-interpreter instead of being global. Once
a subproject interpreter succeed, values from its 'build' object are
merged back into its parent 'build' object.
This allows using the imperfect profiles generated by multithreaded
programs. Without the argument, GCC fails to load them.
Clang just ignores the argument AFAICT.

Replace '\\' with \\\\ in config values args. Otherwise shlex will
helpfully remove path separators on windows, resulting in values like:
`-Ic:mydataishere`
fixup! dependencies/base: Replace windows path separators with /
Hotdoc really wants internal links to point to the .md files instead of
the generated names. Which makes sense, as we're currently relying on
the fact that meson only generated .html pages.
Including the following that has come up several times recent:
- How to use codegen for headers (that each target that uses the header
needs the object in it's sources)
- Using custom_targets with multiple outputs
For PE/COFF it is not possible to allow undefined symbols, so do not
try to use the option to do so.
While gcc ld silently ignores it, this is not the case for the llvm
linker.
Fix#4415
When dependency(), find_library(), find_program(), or
python.find_installation() return a not-found object and disabler is
true, they return a Disabler object instead.
Remove the code responsible for implicitly compressing manpages as .gz
files. It has been established that manpage compression is a distro
packager's task, with existing distros already having their own
implementations of compression.
Fixes#4330
If the directory exists we early return or raise exception in resolve()
method. It was already like that even before the recent refactoring of
the code.
It is safer like that anyway, we don't want a project reconfigure to
silently pull new code. Updating subprojects should be an explicit
action of the user. For example gst-build has a 'git-update' script that
does that. In the future we could add a 'meson subprojects update'
command.
It is sometimes important to be able to build projects offline, in that
case subproject tarballs and patches could be shipped directly within
the project's repository.
