This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
Subprojects that use the CMake PCH feature will cause
compilation/linker errors. The CMake PCH support
should thus be disabled until this can be properly
translated to meson.
There really isn't any reason to not always create missing
include directories inside the build dir. Just restricting
this to generate generated sources should work in an ideal
world, however, there exists lots of suboptimal CMake code
where this assumption is not always true.
It's not enough to detect that the linker is ld64: gcc, icc, and vanilla
clang all use ld64 on macoOS. Instead we have to detect the class of the
compiler, and determine if it's an Apple Compiler or a vanilla one.
Without this, MSVC and MSVC_VERSION won't be set by CMake during
platform detection, and the compiler will be an undefined mixture of
GNU and MSVC. In particular, find_package(opencv) will fail on Windows
when building with MSVC.
This is required to make `-include /path/to/custom/target.hpp`
work. This setup is used by wxWidgets and this PR is
required to use wxWidgets as a CMake subproject.
Otherwise we can end up finding dependencies from the build machine for
the host machine, which is incorrect. This alters cmake, pkg-config, and
all config-tool based dependencies.
Fixes: #7276
This is done with the new cmake subprojects options object
that is similar to the already exisiting configuration data
object. It is consumed by the new `options` kwarg of the
cmake.subproject function.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082

For instance if C:/Program Files (x86)/folder is passed to _guess_files, it would resolve to ['C:/Program Files', '(x86)/folder'] since C:/Program Files is an actual file location that can exist.
