Change the default value of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF` to
restore compatibility with behavior of CMake 3.15 and below.
C++ source files that are generated by Qt's meta object compiler (moc)
include the header file that was passed as input argument to moc. This
is usually a path relative to the source directory, for example
#include "../../source/dir/myobject.h"
That is problematic for reproducible builds as described in #18815.
To cope with that, the target property AUTOMOC_PATH_PREFIX was
introduced in CMake 3.16 by commit d018d27c10 (Autogen: Add moc path
prefix generation (AUTOMOC_PATH_PREFIX), 2019-09-13, v3.16.0-rc1~94^2~4).
The property is default-initialized from the variable
`CMAKE_AUTOMOC_PATH_PREFIX`, which defaults to `ON`.
If this property is ON, and myobject.h is located in an include
directory of the target, moc-generated C++ files include the file
without the "path prefix":
#include "myobject.h"
This behavior, however, can break projects that have equally named
header files in different include directories. As "not breaking
existing projects" trumps "have reproducible builds by default" we
change the default of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF`.
Also, it is now possible to pass `-DCMAKE_AUTOMOC_PATH_PREFIX=ON` on the
CMake command line. Before, it was overridden in `CMakeGenericSystem`.

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.
Fixes: #21017, #20965
Issue: #19391
When `CMAKE_OSX_ARCHITECTURES` is not specified, we add the Xcode
setting `ONLY_ACTIVE_ARCH = YES` with the intention of targeting the
native architecture of the host. However, the default `ARCHS` value
chosen by "Xcode 12 Universal Apps" includes multiple architectures.
Add an explicit `ARCHS` setting with value `$(NATIVE_ARCH_ACTUAL)`
to tell Xcode to use the host's native architecture only.
Fixes: #20893
Allow to specify both DIRECTORY and TARGET_DIRECTORY at the same time in
`set_source_files_properties()` and `set_property(SOURCE)` commands.
Add test cases and update the documentation.
Fixes: #20932
Clarify the order in which --resource-spec-file, RESOURCE_SPEC_FILE,
and CTEST_RESOURCE_SPEC_FILE are searched, and add tests to
enforce this.
Fixes: #20914
The FILES and DIRECTORY options were renamed in bbcff21f71
(file(ARCHIVE*): Collapse FILES and DIRECTORY options, 2020-06-30),
but the synopsis part of the file() documentation was missed.
The synopsis also typically only shows the mandatory options.
Update the synopsis to reflect the name changes and omit the
DESTINATION option since it is not mandatory.
The two options were concatenated internally for both ARCHIVE_CREATE
and ARCHIVE_EXTRACT. The distinction between files and dirs was not
meaningful. Therefore, replace them with PATHS or PATTERNS
to more accurately describe the way the options are used.
Fixes: #20884
In commit a6fee09484 (file: Add CONFIGURE subcommand, 2020-03-06,
v3.18.0-rc1~584^2) we accidentally treated relative path outputs
with respect to the current working directory. Treat them with
respect to the current binary directory instead.
Fixes: #20885
If `get_target_property` fails to find a value for a non-inherited
property, it appends `-NOTFOUND` to the var name and sets that as the
result, rather than setting the value of the var to `NOTFOUND`.
The release notes need to make sense to people not so familiar with
each item. For those less familiar with RPM, spelling out "transaction"
makes this line item much clearer in isolation.
The ability to disable adding architectures completely for packaging purposes
and cases requiring passing the architectures flags explicitly has been
requested.
Support a false value for CUDA_ARCHITECTURES and CMAKE_CUDA_ARCHITECTURES
for this purpose.
Implements #20821.
On scattered installations version.txt and nvvm are located at this location.
This may be useful to users and will allow us in the future to parse
version.txt instead of invoking nvcc to figure out the CUDA toolkit version.
We also add it to CMakeDetermineCUDACompiler in preparation for future use by
Clang code.
