This enables cross-reference syntax for CMake generator expressions:
:genex:`SOME_GENEX`
:genex:`$<SOME_GENEX>`
:genex:`$<SOME_GENEX:...>`
and definition of CMake generator expressions via a directive:
.. genex:: SOME_GENEX
.. genex:: $<SOME_GENEX>
.. genex:: $<SOME_GENEX:...>
It also adds generator expressions defined by the directive and by
`Help/genex/SOME_GENEX.rst` documents to the index.
This was accidentally left out of commit 8acf46caf1 (Utilities/Sphinx:
Add role and directive for 'envvar' in CMake domain, 2018-04-19,
v3.12.0-rc1~200^2~1).
When building and testing CMake in a container with qemu
user mode emulation, the expected termination with std::abort()
in testUVProcessChainHelper leads qemu to emit an additional
message about an uncaught signal. There appears to be no way
to make qemu shut up, so any qemu message will be removed
from the output during validation.

Introduce the function cmReadGccDepfile that parses a GCC-style depfile
and returns its content. The implementation uses a lexer that is
modeled after the re2c implementation in Ninja.
The sample files of the autotest have been created with gcc 8.3.0.
This depfile reader is to be used by the Autogen facility to make use
of the depfiles that are generated by Qt's meta object compiler.
Some compilers do not like the nested `{{{}}}` member initialization
syntax, so use just `{}`. GCC 4.8 warns about the latter, so add a
suppression.

The test for cm::optional assumed that *opt would return a reference
to a non-constructed object if opt.has_value() is false. However, on
certain systems that build CMake with flags to harden the build,
this condition aborts rather than returning the invalid reference.
Fix this by getting the reference only when the cm::optional is
known to actually have a value.
Fixes: #19964
The `PROCESSES` test property name added for CMake 3.16 is too close to
the existing `PROCESSORS` test property. Furthermore, the property in
principle specifies groups of resources organized in a way that is
meaningful to a particular test. The groups may often correspond to
processes but they could have other meanings. Since the property name
`PROCESSES` has not been in a final 3.16 release yet, simply rename it
to `RESOURCE_GROUPS`.

Manual tracing of all call sites shows that all values are initialized.
This algorithm is used to determine whether or not a test can
execute with the available resources. It uses a recursive largest-
first algorithm to try to place the tests into their respective
slots.
