Currently if you change the `choices` field in the meson_options.txt
file, no update will be done until `meson setup --wipe` is called. Now
if the choices change then the options will be properly merged.
If the currently select value is still valid it is guaranteed to be
kept, if it is now invalid the new default value will be used and a
warning will be printed.
Fixes#7386
`pathlib.Path.glob()` also returns directories that match source
filenames (i.e. a directory named `test.h/`), but `clang-format` and
`clang-tidy` fail when handed a directory. We manually skip calling
`clang-format` and `clang-tidy` on those directories.
This is required to make the various keys in the [user options] section
work the same as they do in the meson_options.txt file, where we don't
have any rules about case sensitivity.
There is some risk here. Someone may be relying on this lower by default
behavior, and this could break their machine files.
Fixes#7731
Projects that specify b_pie=true clutter build logs with the warning:
clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument]
No option is needed to produce PIE binaries because ld64 is making PIE
executables on 10.7 and above by default, as documented in ld(1).

The implementation of the link variant was what should have been the
compiler variant, and there was no valid compiler variant, which meant
it was getting C code.
This abstraction is really useful, and most compilers could use it
(including D). It also will allow the Gnu mixins to work properly
without the CLikeCompiler in their mro.
So that we can actually use it anyplace that an OptionDictType could be
used. I've also done a bit optimizing/simplifying of the implementation.
This is needed for cuda, as it returns an OptionOverrideProxy where we
ask for an OptionDicType
So that every subclass doesn't have to reimplement it. Especially since
the Gnu implementation moved out of the CCompiler and into the
GnuLikeCompiler mixin
with msys ncurses-config returns a unix style path (currently, though
it's been fixed upstream), which the compilers don't understand, so we
can't do that. Additionally, while the system search does work, there's
missing include directories that need to be added.
On win32 there is pdcurses, so we detect it first, because python
depends on ncursesw, so if we don't want to use ncursesw, we should make
sure pdcurses detect before ncursesw
has_header returns a tuple of (found: bool, cached: bool), so `if
has_header` will always return true because the tuple is non-empty. We
need to check if the found value is true or not.
- Fixed using debug and optimization built-in options in MSVC.
- Fixed that VS backend does not create pdb files in release mode.
VS implicitly adds the debug fields if left out.
- Fix that it is possible to add debug info with ninja backend with
optimizations.
When building with vs2019 (not ninja), a path length error will be thrown
if the path to a resource file is even remotely deep within the tree.
This is largely because the target name includes the string "Windows
resource for file 'full path'", which is then expanded twice (once for
the .vcxproj itself, and once for IntDir) and added to the full path.
When combined with the tiny path limits on Windows, it is easy to exceed
path limits.
This error is largely avoided by the ninja back-end. Unlike the
vs back-end, the ninja back-end does not use target.get_id() as part of
the project file path, nor does it use target.get_id() as part of
get_target_private_dir().
