We used to detect the `rcc` features before every `rcc` list invocation
wich resulted in `rcc` be called twice for every listing operation.
Now we detect the `rcc` list capabilities once during configuration and
pass it to the cmake_autorcc target in the info file.
Instead of processing all `rcc` invocation requests in the
_autogen target that calls `cmake -E cmake_autogen ...` once,
use a dedicated custom command that calls
`cmake -E cmake_autorcc ...` for each `.qrc` file.
This allows parallel `.qrc` file processing and reduces the
workload (and complexity) in the _autogen target.
If only `AUTORCC` is enabled, the _autogen target won't be created
at all since it is now used for `AUTOMOC` and `AUTOUIC` only.
For `.qrc` files that are GENERATED a custom target is used
instead of a custom command.
Closes#17161
Introduces the standalone RCC generator class `cmQtAutoGeneratorRcc`.
Every instance of `cmQtAutoGeneratorRcc` class handles the
`rcc` invocation for a single `.qrc` file.
The class will be used in the future to allow parallel `.qrc` file
processing by calling `cmake -E cmake_autorcc <INFO_FILE> <CONFIG>`.
When rejecting the `COMPILE_LANGUAGE` generator expression on include
directories and compile definitions with Xcode, add `file(GENERATE)` to
the allowed set in the message. It is allowed and already covered
by the `RunCMake.File_Generate` test `COMPILE_LANGUAGE-genex` case.
This reintroduces the change from commit v3.10.0-rc1~69^2 (Performance:
Improve efficiency of source file lookup in cmMakefile, 2017-08-17) with
some corrections. The original was rolled back by commit
v3.10.0-rc1~52^2~1 (Revert "Performance: ...", 2017-09-25) due to
incompatibilities found. The rollback was followed-up by addition of a
test for the offending case, and this revision passes the test.
After the refactor to make CTest use std::chrono::steady_clock for the
keeping of time for test duration, there are still references to
cmSystemTools::GetTime() left.
To further adopt std::chrono for time related activities, this commit
changes those remaining references to std::chrono::system_clock::now()
calls and alters the storage from either unsigned int or double to
std::chrono::system_clock::time_point.
For ease of conversion, a converter method is added to cmXMLWriter that
converts from a std::chrono::system_clock::time_point to the number of
seconds since the UN*X epoch as that is expected behaviour. This means
no more casts as required.
Functionally should be no difference as the system_clock is implemented
in the same terms.

Do not obscure IWYU's report with warnings from its internal Clang.
We have other testing for such warnings. Also, when compiling with
a non-Clang compiler we might use warning options that IWYU's Clang
does not understand, and we don't want to see warnings about that.
Add test for a case fixed by commit 6a4a61d9e1 (cmForEachCommand:
prevent leakage, 2017-10-09). Prior to that fix, this test case
could trigger an assertion failure.

When using a real MSVC compiler for `C` or `CXX`, use the version of
that compiler for `MSVC_VERSION`. This is preferred over the MSVC
version that a non-MSVC compiler "simulates".
Fixes: #17468
Since commit v3.10.0-rc5~3^2 (FindOpenGL: Default to non-GLVND libraries
for legacy GL, 2017-11-08) users may set `OPENGL_gl_LIBRARY` to empty to
use GLVND components for the legacy GL interfaces. This is useful only
when one knows in advance that the GLVND components will be found.
Add a `OpenGL_GL_PREFERENCE` variable to specify a preference for legacy
GL or GLVND. The latter can suppress `OPENGL_gl_LIBRARY` only when the
needed GLVND components are found. If no preference is explicitly
specified, choose a default based on whether GLVND components were
requested (because this indicates the project has been updated for
CMake 3.10).

If the value of `CMAKE_HOST_SYSTEM_PROCESSOR` also happens to be set as
a variable by a project (e.g. `AMD64`), allowing `if()` to
auto-dereference is unlikely to produce a value that matches "64".
Instead let `if()` auto-dereference `CMAKE_HOST_SYSTEM_PROCESSOR`.
Fixes: #17460
If the compiler given in I_MPI_... could not be found, the Intel MPI
wrappers emit an error like "line 590: ifort: command not found".
The script should currently fail to match the output of this for
information, but we should generally treat such an output as invalid,
since the displayed configuration line can become a mixup between Intel
and GNU compiler settings.
OpenMP libraries must always be found in the implicit linking
directories of a compiler when using the OpenMP compile flag. If a suitable OpenMP library is also found in for example some CMAKE_PREFIX_PATH, this can lead to the module finding the incorrect library.
On the other hand, CMAKE_PREFIX_PATH can't ever be a location that we
need to consider since the OpenMP compile flag would not work if we
needed to.
