The new ``cmQtAutoGenInitializer::InfoWriter`` class provides an
interface to write strings/vectors/sets/maps in CMake format
into a file. Its use replaces various `cmJoin` calls that
failed to address escaping of semicolons in list elements.
Closes#18554
This teaches CMake the variables
- CMAKE_GLOBAL_AUTOGEN_TARGET
- CMAKE_GLOBAL_AUTOGEN_TARGET_NAME
- CMAKE_GLOBAL_AUTORCC_TARGET
- CMAKE_GLOBAL_AUTORCC_TARGET_NAME
which control the generation of global
``autogen`` and ``autorcc`` targets.
Closes#17721
This adds
- the variable ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` which initializes
- the target property ``AUTOGEN_ORIGIN_DEPENDS``
which controls whether or not the origin target dependencies
should be forwarded to the corresponding ``_autogen`` target.
The default value of ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` is ``ON``
which corresponds to the behavior that is in place since CMake 3.9.
Closes: #18493
cmQtAutoGenInitializer::InitCustomTargets and
cmQtAutoGenInitializer::SetupCustomTargets
now return their success value which gets evaluated
and passed on by the caller (cmGlobalGenerator).
Checks for the existance of the moc/uic/rcc
binaries have been introduces in cmQtAutoGenInitializer.
Additionally they get called once with a "-h"
argument to determine if they're functional.
This way any binary-not-found problem is caught
during the configuration phase.
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
