This sets variables like PROJECT_HOMEPAGE_URL, which can be
used as default values for various things (packaging modules,
doxygen defaults, etc.). Some packaging modules have been
updated to do this as part of this commit.

This feature was originally added by commit v3.9.0-rc1~71^2~2 (find_*:
Add a new PackageRoot search path group, 2017-05-03) and documented by
commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search path
group, 2017-05-03). However, we had to disable the feature and remove
the documentation in commit v3.9.1~2^2 (find_*: Disable the PACKAGE_ROOT
search path group for CMake 3.9, 2017-08-08) due to breaking projects
that used `PackageName_ROOT` variables themselves.
Add policy `CMP0074` to restore the `PackageName_ROOT` variable behavior
in a compatible way. Also revise the stack of root paths to store the
paths themselves rather than the package names. This way the policy can
be considered at the `find_package` call site instead of individual
`find_` calls inside a find module.

Issue: #17144
This change introduces an additional property that may be set on a
target to allow additional properties to be exported. Normally only a
limited number of properties are exported.
Additional properties may be exported by simply setting the
`EXPORT_PROPERTIES` property on a target that is exported.
Features recorded by commit v3.6.0-rc1~120^2~5 (Features: Record
standards and features for Intel C++ on UNIX, 2016-04-28) for the Intel
compiler left out initializer list support because our test case in
`Tests/CompileFeatures/cxx_generalized_initializers.cpp` caused an
internal compiler error. It turns out this is because the Intel
compiler asserts the `initializer_list` constructor signatures to verify
that they match its own `<initializer_list>` header. It was our dummy
implementation used to test the language feature without any headers
that caused the ICE. Revise it to use a constructor signature accepted
by the Intel compiler.
Fixes: #17829
In gtest_discover_tests(), the TIMEOUT keyword was making it
impossible to set the TIMEOUT test property via the PROPERTIES
keyword. This would be a frequent case, but it doesn't complain
and instead silently does something different to what would
normally be expected. The TIMEOUT keyword has been renamed
to DISCOVERY_TIMEOUT, thereby removing the clash.
This is a breaking change. 3.10.1 and 3.10.2 were the only versions
that supported the TIMEOUT keyword and uses of it were likely
not working as intended.
Fixes: #17801
The IBM XL C compiler does not define `__STDC__` when invoked as plain
`cc` instead of `xlc`, so `CMAKE_C_STANDARD_COMPUTED_DEFAULT` does not
get set and CMake fails. Teach CMake about the XL compiler's default C
standard in this case.
Fixes: #17649
Options specified via `COMPILE_OPTIONS` and `INTERFACE_COMPILE_OPTIONS`
are deduplicated, but individual options can legitimately be duplicated
when grouped with other options, e.g.
-D A -D B
After deduplication that becomes `-D A B`. Therefore we need a way to
treat groups of options as units during deduplication. A simple approach
is to specify each group as one option, e.g.
"-D A" "-D B"
However, that conflicts with options that legitimately have spaces. To
break this ambiguity, add a `SHELL:` prefix syntax to specify that an
option should be parsed like shell command line arguments after
deduplication, e.g.
"SHELL:-D A" "SHELL:-D B"
These will survive deduplication intact, and then be parsed to produce
`-D A -D B` on the final command line.
Fixes: #15826
The docs for CMAKE_PROJECT_NAME and CMAKE_PROJECT_DESCRIPTION
were erroneously documenting the behavior of PROJECT_NAME and
PROJECT_DESCRIPTION respectively. Fix these and update the
project() docs to also mention CMAKE_PROJECT_NAME and
CMAKE_PROJECT_DESCRIPTION.
