The computation of additional source headers and and private headers for
AUTOGEN is moved from the _autogen target to the configuration stage. This
makes them available for _autogen target dependency computations.
Closes: #18949
In AUTOGEN this replaces simple file name lists with two list (for
headers and sources) of structs with file name and file flags.
The file name lists that are passed to the _autogen target via
AutogenInfo.cmake are filtered from these two lists.
This adds support for AUTOMOC to moc header files with the same but different
extensions (e.g `obj.h`, `obj.hpp`, `obj.hxx`). If a moc file would appear
multiple times in `mocs_compilation.cpp`, a number suffix is appended
to the name to make it unique.
Closes#14489
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
On Windows systems we used to add a "-DWIN32" definition to the ``moc``
defines. This is not necessary anymore when we have a
``moc_predefs.h`` file that provides all compiler predefines.
Closes#18623
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

The output of moc/uic/rcc used to be discarded unless
the program failed. This lets moc/uic/rcc print their
output to stdout even on success.
Closes#17860
For multi configuration generators AUTOMOC generates the
moc files that are included in `mocs_compilation.cpp`
in `AUTOGEN_BUILD_DIR/include_$<CONFIG>/`. By doing so each
configuration reads different moc files when compiling
`mocs_compilation.cpp`. Since we do not (need to) rewrite
`mocs_compilation.cpp` on a configuration change anymore,
the files also does not need to be recompiled anymore.
Not having to rewrite and recompile `mocs_compilation.cpp`
on a configuration change anymore was the main objective of
this patch.
In a similar fashion AUTORCC generates a `qrc_BASE_CMAKE.cpp`
file below `AUTOGEN_BUILD_DIR/include_$<CONFIG>/` and
`qrc_BASE.cpp` becomes a mere wrapper that includes this
actuall rcc output file (when using multi configuration
generators).
The template files `Modules/AutoRccInfo.cmake.in` and
`Modules/AutogenInfo.cmake.in` were removed in favor
of writing the info `.cmake` files manually.
Closes#17230
When moc/uic include was found on the first line of
a file it was ignored. This fixes the issue by extending
the regular expression for include detection.
Closes#17655
This introduces concurrent thread processing in the `_autogen`
target wich processes AUTOMOC and AUTOUIC.
Source file parsing is distributed among the threads by
using a job queue from which the threads pull new parse jobs.
Each thread might start an independent ``moc`` or ``uic`` process.
Altogether this roughly speeds up the AUTOMOC and AUTOUIC build
process by the number of physical CPUs on the host system.
The exact number of threads to start in the `_autogen` target
is controlled by the new AUTOGEN_PARALLEL target property which
is initialized by the new CMAKE_AUTOGEN_PARALLEL variable.
If AUTOGEN_PARALLEL is empty or unset (which is the default)
the thread count is set to the number of physical CPUs on
the host system.
The AUTOMOC/AUTOUIC generator and the AUTORCC generator are
refactored to use a libuv loop internally.
Closes#17422.
