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.
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.
In commit v2.8.0~170 (ENH: Added ctest test options PROCESSORS and
RUN_SERIAL, 2009-09-07) CTest learned to track the number of processors
allocated to running tests in order to balance it against the desired
level of parallelism. Extend this idea by introducing a new
`PROCESSOR_AFFINITY` test property to ask that CTest run a test
with the CPU affinity mask set. This will allow a set of tests
that are running concurrently to use disjoint CPU resources.
239a3ef8 Server-mode: Document protocol version for optional handshake arguments
9b1a3d24 Server-mode: Rename functions to reflect what they do
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !1693
Document which Protocol version only needs the build directory to be passed
during a handshake.
This is available a bit earlier than that, but from all I can tell 1.2 is
the earliest version where that feature is reliably available.
The last KDevelop3 release was many years ago, in 2008 I think.
I haven't seen or read about anybody using KDevelop 3 since a
long time, so I think it can safely be removed from CMake.
KDevelop 4 (first released in 2010) has its own proper CMake
support now, independent from this generator.

The set of compile flags used for a target's C and C++ sources is based
on the linker language. By default this is always the C++ flags if any
C++ sources appear in the target, and otherwise the C flags. Therefore
we can define the `COMPILE_LANGUAGE` generator expression in
`INCLUDE_DIRECTORIES` to match the selected language.
This is not exactly the same as for other generators, but is the best VS
and Xcode can do. It is also sufficient for many use cases since the
set of include directories for C and C++ is frequently similar but may
be distinct from those for other languages like CUDA.

Issue: #17435
This removes duplicated code for per-config variable initialization by
providing a `cmake_initialize_per_config_variable(<PREFIX> <DOCSTRING>)`
function.
This function initializes a `<PREFIX>` cache variable from `<PREFIX>_INIT`
and unless the `CMAKE_NOT_USING_CONFIG_FLAGS` variable is defined, does
the same with `<PREFIX>_<CONFIG>` from `<PREFIX>_<CONFIG>_INIT` for every
`<CONFIG>` in `CMAKE_CONFIGURATION_TYPES` for multi-config generators or
`CMAKE_BUILD_TYPE` for single-config generators.
Backtrace information was included by commit 35a52bd1b4 (server: add
"ctestInfo" request to get test info, 2017-10-25) to match that already
provided for targets. However, the backtrace representation uses too
much memory and needs to be dropped. Remove it from test information.
Issue: #17502
The backtrace information is very repetitive and hugely increases the
size of the codemodel object. We need to remove it until an alternative
representation can be developed. Revert commit v3.10.0-rc1~393^2
(server: Report backtraces in codemodel response, 2017-06-20), except
for the protocol version number (because it indicates other new things).
Unfortunately this is incompatible with clients that expect the
"crossReferences" field in targets. However, the regression in memory
usage is quite serious, especially on large projects, and therefore
breaks even older clients that do not use backtraces. Since the
"crossReferences" field was only provided by one release (3.10.0), it is
simplest to revert it outright for 3.10.1.

This enables configuration of build parallelism with the Ninja generator by
passing arguments on the command line to CMake. For example,
cmake \
'-DCMAKE_JOB_POOLS:STRING=compile=5;link=2' \
-DCMAKE_JOB_POOL_COMPILE:STRING=compile \
-DCMAKE_JOB_POOL_LINK:STRING=link \
~/src/MyProject
