Since commit v3.11.0-rc1~433^2~2 (Teach target_* commands to set
INTERFACE properties of IMPORTED targets, 2017-09-18) it is now possible
to use the customary `target_*` commands for adjusting the settings of
an IMPORTED target. Update documentation accordingly.

6e190d9a Fix include directory usage requirement for build tree
6d4e9fde SystemInformation: Android has no getifaddrs prior to API 24
0a0974d0 SystemTools: Restore unconditional caching in GetActualCaseForPath
a241fd13 SystemTools: Remove caching from public GetActualCaseForPath
Calling `std::string::front()` on an empty string results
in an undefined behavior by the C++ standard.
In gcc8 it causes an assertion to fail.
This adds a check to `AUTOGEN` if a file to read is empty
and in case avoids the use of an empty `std::string` buffer.
Closes#17793
IBM XL C/C++ for Linux versions 13.1.6 and above no longer define
`__IBMC__` or `__IBMCPP__` by default (see `-qxlcompatmacros`).
Instead `__ibmxl__` now identifies the compiler along with some
related new version macros.
Fixes: #17784
Refactoring in commit v3.11.0-rc1~293^2~4 (Modules: Remove paths set as
global Unix prefixes, 2017-11-20) removed `PATH_SUFFIXES` options that
appeared to be used to cover subdirectories of the `PATHS` options that
were also removed. However, the path suffixes also apply to other
search paths and so should not be removed. Restore them.
Fixes: #17760
The test was expecting timestamps on day 1 in 1970 to start at 86400 but
they actually started at 0. This worked without `SOURCE_DATE_EPOCH=1`
because after 1972, leap days compensated the offset.
Fixes: #17762
In case CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY has been enabled
generate only the root-level ZERO_CHECK target so targets in
subdirectories pick up the root generator target of ZERO_CHECK.
For the case that CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY is not
enabled more investigation and a proper and final fix is still needed.
Issue: 14297
Some environments require linking to thread libraries for `std::thread`.
Express this direct dependency of CMakeLib explicitly. Previously this
was done indirectly through our bundled libuv, but that does not work
when using a system libuv.
Fixes: #17757
`Modules/CMakeCCompilerId.c.in` will report the C dialect as 11 whenever
`__STDC_VERSION__` indicates *at least* C 11. Make the test consistent
with this. We already do this for the C++ case.
Fixes: #17740
In commit v3.11.0-rc1~466^2 (Compiler/TI: Add support for depfile
generation for Ninja, 2017-10-16) the flag for C++ was added in a
variable with a typo in its name. Fix the spelling.
Issue: #17360
The `LINK_ONLY` generator expression is used to represent private
dependencies of static libraries in their `INTERFACE_LINK_LIBRARIES`
property value. Fix evaluation of generator expressions during export
to support the `LINK_ONLY` genex. Extend the RunCMake.AndroidMK test
with a case for this.
When exporting `INTERFACE_LINK_LIBRARIES`, we must evaluate generator
expressions first, before expanding the `;` list, in case they contain
or generate semicolons.
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.
