This removes duplicated code for per-config variable initialization by
providing a `cmake_initialize_per_config_variable(<PREFIX> <DOCSTRING>)`
function.
This function initializes a `<PREFIX>` cache variable from `<PREFIX>_INIT`
and unless the `CMAKE_NOT_USING_CONFIG_FLAGS` variable is defined, does
the same with `<PREFIX>_<CONFIG>` from `<PREFIX>_<CONFIG>_INIT` for every
`<CONFIG>` in `CMAKE_CONFIGURATION_TYPES` for multi-config generators or
`CMAKE_BUILD_TYPE` for single-config generators.

This is more or less what Gentoo implements for years, but in a more
sophisticated version that uses the target mode now offered by
pkg_check_modules().
Added support for QT IFW "RemoveTargetDir" boolean option. QTIFW
supports an option to prevent, or not, deletion of the installation
directory. This is a direct pass-through to that variable.
7ab9a625 Makefiles: Drop 'requires' step and its supporting infrastructure
5f2e2c38 Makefiles: Avoid nested make calls for Fortran module dependencies
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !1523
The 'requires' step was used to provide implicit dependencies between
the generated Fortran module files and a Fortran target that needs these
module files to ensure the correct compilation order. After recent
refactoring to resolve all dependencies explicitly through `.mod.stamp`
make targets, the separate 'requires' step is not needed anymore.
`libgfxoffload` is only used and installed by the Intel C/C++ compilers
and will be unavailable if only Intel Fortran has been installed.
Fixes: #17550
This MR fixes a number of bugs stemming from legacy variable handling,
partially introduced by commit v3.10.0-rc1~103^2 (FindMPI: Add support
for FreeBSD and SLES, 2017-08-09).
* `MPI_COMPILE_OPTIONS` and `MPI_COMPILE_DEFINITIONS` legacy hints were not passed correctly.
* Legacy variables could be parsed after they were set by `FindMPI` cause erroneous hinting on subsequent runs.
* In the case of the compiler supporting MPI implicitly:
* not all consumption variables would be correctly reset.
* `MPI_<LANG>_HEADER_DIR` would be set unintentionally.
* `MPI_<LANG>_LIB_NAMES` appeared in cache despite being ignored.
* on subsequent passes, `MPI_<LANG>_COMPILER` could be corrupted.
* the C-to-CXX copy logic would take place even if `MPI_SKIP_GUESSING` was turned on
* if only some language compilers were given, inconsistent search behavior could be observed
Issue: #17538
The IAR compiler test works when a project specifies LANGUAGES C CXX
but fails if CXX comes before C. This change makes it work regardless
of the order.
