Previously we would synthesize <TARGET_NAME>-NOTFOUND as the location. This
would then end up on the link line and cause build failures.
Policy CMP0110 is added to control this behaviour.
Fixes#19080, #19943.
Since commit f7347f28c7 (MSVC: Record support for C11 and c_restrict,
2020-08-09) we know about MSVC C language standards. Update the
`RunCMake.try_compile` test to be aware of this even when CMake is
itself configured by an older CMake that does not know this.
Output files get the source property `GENERATED` which is indirectly
checked by adding them to a library.
For a missing file that is not generated CMake will abort.
With the new behavior according CMP0070 relative files are generated
into the binary directory.
The XcodeRemoveExcessiveISystem test runs
`find_package(ZLIB)` which returns an SDK-relative
path to `zlib.tlb`. When the test switches the SDK
for building to something different than the SDK used
for configuration the linker rightfully complains about
the mismatch.
The fix is to configure and build with the same SDK.
Add an `OPTIMIZE_DEPENDENCIES` target property and supporting
`CMAKE_OPTIMIZE_DEPENDENCIES` variable to optionally enable pruning and
flattening of outgoing dependencies from static libraries. Since they
do not actually link, they only depend on side effects of their
dependencies. Therefore we can drop dependencies that contribute no
side effects.
Restore the change from commit f84af8e270 (add_test: Allow special
characters in test name, 2020-05-16, v3.18.0-rc1~142^2) that had to be
reverted by commit f84af8e270 (add_test: Allow special characters in
test name, 2020-05-16, v3.18.0-rc1~142^2) for compatibility.
Add policy CMP0110 to make the change in a compatible way.
Also, support even more characters than before by generating the
test scripts using bracket arguments around the test names.

INTERFACE libraries with SOURCES now appear in the generated
buildsystem, so include them in the codemodel output too.
We do not need to bump the `codemodel-v2` object kind minor
version because that was already done in post-3.18 development
by commit 7d6861f367 (fileapi: Extend codemodel targets with
language standard, 2020-06-18).
Fixes: #18608
INTERFACE libraries were created with the intention of collecting usage
requirements for use by other targets via `target_link_libraries`.
Therefore they were not allowed to have SOURCES and were not included in
the generated buildsystem. In practice, this has become limiting:
* Header-only libraries do have sources, they just do not compile.
Developers should be able to edit those sources (the header files)
in their IDE.
* Header-only libraries may need to generate some of their header
files via custom commands.
Some projects work around these limitations by pairing each interface
library with an `add_custom_target` that makes the header files and
custom commands appear in the generated buildsystem and in IDEs.
Lift such limitations by allowing INTERFACE libraries to have SOURCES.
For those with sources, add a corresponding build target to the
generated buildsystem.

When using Qt 5.15.0 or above together with Ninja, check that touching
a source file of a dependency does not needlessly re-run AUTOMOC for
the dependee target.
Previously we disallowed use of arbitrary properties on INTERFACE
libraries. The goal was to future-proof projects using them by not
allowing properties to be set that may affect their future inclusion in
the generated buildsystem. In order to prepare to actually include
INTERFACE libraries in the generated buildsystem, drop the filter and
allow arbitrary properties to be set.

Revert commit f84af8e270 (add_test: Allow special characters in test
name, 2020-05-16, v3.18.0-rc1~142^2). Unfortunately the fix breaks
projects that were working around the limitation with manual escaping.
The fix can be re-introduced with a policy in a future version.
Also add a 3.18.1 release note explaining the change.
