Ninja runs just one command line for every build statement, so the Ninja
generator needs to `&&`-chain multiple commands together into one long
string. For long custom command sequences this can exceed the maximum
command-line length for the operating system. In such cases, write the
commands out to a script instead, and then run the script from Ninja's
one command line.

Fixes: #15612
Check if the content of the AUTOMOC/UIC/RCC info file
will change before overwriting it. This avoids unnecessary
AUTORCC rebuilds when AUTORCC unrelated CMake settings change.
Add `clang` and `clang++` after the corresponding `gcc` and `g++`
candidates. Otherwise it is not tried on platforms where we do not
enumerate the toolchain pair candidates.
Fix logic added by commit 2ee10119ea (swig: fix incremental build in
case of removed interface files, 2017-11-06). Name the extra targets
added for Makefile generators using both the module name and .i base
name to avoid collisions across modules. Also make sure the extra
targets added for all .i files in a module are added as dependencies
instead of just the last one.
Fixes: #17704
For multi configuration generators AUTOMOC generates the
moc files that are included in `mocs_compilation.cpp`
in `AUTOGEN_BUILD_DIR/include_$<CONFIG>/`. By doing so each
configuration reads different moc files when compiling
`mocs_compilation.cpp`. Since we do not (need to) rewrite
`mocs_compilation.cpp` on a configuration change anymore,
the files also does not need to be recompiled anymore.
Not having to rewrite and recompile `mocs_compilation.cpp`
on a configuration change anymore was the main objective of
this patch.
In a similar fashion AUTORCC generates a `qrc_BASE_CMAKE.cpp`
file below `AUTOGEN_BUILD_DIR/include_$<CONFIG>/` and
`qrc_BASE.cpp` becomes a mere wrapper that includes this
actuall rcc output file (when using multi configuration
generators).
The template files `Modules/AutoRccInfo.cmake.in` and
`Modules/AutogenInfo.cmake.in` were removed in favor
of writing the info `.cmake` files manually.
Closes#17230
In commit v3.4.0-rc1~480^2~3 (cmCustomCommandGenerator: Port to
cmOutputConverter, 2015-06-04), cmCustomCommandGenerator's access to the
local generator was removed so it needed to construct its own
cmOutputConverter instance. Access to the local generator was then
restored by commit v3.4.0-rc1~285^2~21 (cmCustomCommandGenerator:
Require cmLocalGenerator in API, 2015-07-25), so now we can use its
cmOutputConverter base class methods directly.
Remove the `PRE_LINK` and `POST_BUILD` variables. They are not
referenced by `WriteDeviceLinkRule`.
Remove the `byproducts` local variable from `WriteDeviceLinkStatement`
and all the code populating it. We never used the result.

The `SWIG_OUTFILE_DIR` variable provides the option to specify an output
directory location. This commit removes portion stating that this is
equal to the `swig -o` option since it does not set the output filename.

Intel MPI on Windows prefixes all outputs with some boilerplate
copyright text. By discarding it, we should prevent any potential
clashes with our regex parsing.
