Commit c389f8bb (cmLocalGenerator: Port Find method away from
GetGeneratorTarget, 2015-10-25) ported the implementation of
FindGeneratorTargetToUse away from the FindTargetToUse method,
but neglected to handle alias targets.
The latter method has a parameter to determine whether to
include alias targets in the search, but as that is only
needed at configure time, this generate-time equivalent does
not need the condition.
c099e00f Access policy status from cmGeneratorTarget at generate time.
d74bca5a cmGeneratorTarget: Copy the policy map from the cmTarget.
c6e86955 cmTarget: Remove unused NameResolvesToFramework.
18046bd5 cmCommonTargetGenerator: Use NameResolvesToFramework without cmTarget.
91411641 Move ComputeLinkType out of cmTarget.
6d94078e cmGeneratorTarget: Move IsDLLPlatform from cmTarget.
3ebc6285 cmGeneratorTarget: Move HaveWellDefinedOutputFiles from cmTarget.
311018e5 cmGeneratorTarget: Move GetExportMacro from cmTarget.
215cd21a cmGeneratorTarget: Provide direct access to the backtrace.
1df8bd3a cmGlobalGenerator: Port IsRootOnlyTarget to cmGeneratorTarget.
83703bda cmGeneratorTarget: Copy IsExecutableWithExports from cmTarget.
Set a cmLocalGenerator on each instance at compute time. That will
soon be needed to access cmGeneratorTarget instances.
If a cmExportBuildFileGenerator is processed early during configure time as a
result of CMP0024 it must be removed from the list to process later at generate
time.
The cmMakefile should get a fully prepared snapshot and not clobber its
definitions. It should eventually be able to process list files from any
starting-point snapshot, though that is some refactoring away still.

The Ninja generator and Visual Studio generators are special-cased for the
QtAutogen feature. In order to reduce the number of custom targets, the Visual
Studio generators prefer to create custom commands instead, and in order to
create appropriate Ninja files, generated rcc files are listed as byproducts.
This requires the use of the GetConfigCommonSourceFiles API of the
cmGeneratorTarget for those generators when initializing the autogen target.
The initializer method is called from Compute() after the cmGeneratorTarget
objects are created, however the initialization of the object directory occurs
later in the InitGeneratorTargets method. That means that the resulting object
locations are computed incorrectly and cached before the object directory is
determined, so the generated buildsystem can not find the object files.
The initialization of the object directory was split from the creation of
cmGeneratorTarget instances in commit 0e0258c8 (cmGlobalGenerator: Split
creation of generator object from initialization., 2015-07-25). The motivation
for the split was to do only what is essential to do early in cases where
cmGeneratorTargets need to be created at configure-time. That is required for
the purpose of implementing policies CMP0024 and CMP0026, and for
try_compile(LINK_LIBRARIES). However, the split was not really necessary.
Compute the object directory in the cmGeneratorTarget constructor instead.
The QtAutogen unit test already tests the use of TARGET_OBJECTS with AUTOMOC,
and that test already passes on Ninja. The reason it already passes is that
the QtAutogen target also uses the AUTORCC feature, and specifies several qrc
files in its SOURCES. Later in the Compute algorithm (after the
InitGeneratorTargets call), the rcc files are determined and target->AddSource
is called. The AddSource call clears the previously mentioned cache of source
files, causing it to be regenerated when next queried, this time taking account
of the object directory.
Extend the test suite with a new target which does not make use of AUTORCC with
qrc files so that the test added alone would break without the fix in this
commit.
Ensure that all targets have their _automoc.cpp before attempting
to initialize the autogen target. The initialization evaluates
generator expressions for target sources, and must include the
_automoc.cpp of object library dependents in order for TARGET_OBJECTS
to include the object file for the corresponding _automoc.cpp file.
