This is a large commit that serves multiple purposes
- Iterate source files only once and store all extracted
information in a cmQtAutogenDigest class that can be reused.
This is brings speed improvements because several properties
are only evaluated once. More that that it helps to avoid
duplication of code with non trivial files property checks.
- Fix the Visual Studio generator to use PRE_BUILD when possible.
- Convert `for( ... )` loops to C++11 range base loops where possible
(cmQtAutogen*.cxx only).
- String concatenation optimizations.
This allows to pass SKIP_AUTOMOC hints to the
FOO_autogen target from files that are not listed
in the target sources.
The problem was that if main.cpp was listed in the source
but not main.h, then SKIP_AUTOMOC for main.h was ignored.
Adds cmGeneratorTarget::clearSourcesCache() which clears the cache
of precomputed sources lists and object names. The cache gets
recomputed on demand.
Clearing the cache is necessary in case an OBJECT library
gets a source added after a target (ORIGIN) that includes it
computed it's external sources cache.
This may happen in AUTOMOC when ORIGIN is processed before the
OBJECT library which gets a mocs_compilation.cpp file added.

For multi configuration generators remove per-config
qrc_FOO_$<CONFIG>.cpp source file support.
Instead use a single source file qrc_FOO.cpp which is a wrapper
that includes the actual rcc generated qrc_FOO_CONFIG.cpp file.
This way, after a repeated configuration change, only the wrapper file
qrc_FOO.cpp must be regenerated to include the appropriate
qrc_FOO_CONFIG.cpp file.
Only the dependecies from target_link_libraries() of the origin
target were forwarded to the _autogen target. This patch
adds forwarding of the dependencies from add_dependencies()
to the _autogen target.
Closes#17094
This lets AUTOMOC and AUTOUIC process GENERATED files which
used to be ignored before.
A new policy CMP0071 ensures that the old behavior of ignoring
GENERATED files is enabled when the CMake compatibility version
CMAKE_MINIMUM_REQUIRED is < 3.10.
Closes#16186
The change in commit v3.9.0-rc1~464^2~8 (Autogen: Add AUTOMOC/UIC
support for generated source files, 2017-03-02) changes behavior of
existing projects that may not expect `AUTOGEN` on generated files and
do not yet set `SKIP_AUTOGEN` on them. Disable the behavior change for
now to fix the regression for CMake 3.9. We can restore it later with a
policy.
In order to keep the implementation and tests working, add an
undocumented property we can use in the tests to enable the behavior
before the policy is introduced.
Fixes: #17031
Issue: #16186
The change in commit v3.9.0-rc1~42^2~1 (Autogen: Per-config file
suffixes, 2017-05-15) broke Visual Studio builds because the generators
do not yet fully support per-config sources. Disable the behavior on
Visual Studio generators for now.
Fixes: #16939
Qt is relying on whoever calls moc to include a file with the predefined
values that will be used by the compiler, otherwise moc takes wrong
paths and weird things happen.
Instead, generate an include file and feed it to all mocs to make sure
it's generating correct code.
