On some systems, ${QT_INCLUDE_DIR} is reported by gcc as a builtin
include search dir. Some projects use this information to extend
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES.
In cmake 2.8.10 now the targets are queried for the include directories
they use. When they return the result, the include dirs contained in
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES have been removed.
In cmake 2.8.9 and below the INCLUDE_DIRECTORIES directory property
was queried, where this had not been stripped.
So, in those projects which modify the implicit include dirs variable,
on systems where ${QT_INCLUDE_DIR} is reported by gcc, this directory,
e.g. /usr/lib/include/qt/, was not given anymore to moc. This made moc
not find required headers, so the build broke.
Simply giving the full CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES to moc
is no solution either, since moc can't handle some of the headers it
finds then (https://bugreports.qt-project.org/browse/QTBUG-28045).
So now cmake checks CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, and if this
contains ${QT_INCLUDE_DIR}, and the target reports that it uses
${QT_QTCORE_INCLUDE_DIR} but not ${QT_INCLUDE_DIR}, ${QT_INCLUDE_DIR}
is added to the include dirs given to moc.

Since commit 43b74793 (OS X: Further improve default CMAKE_OSX_SYSROOT
selection, 2012-09-21) we choose a default CMAKE_OSX_SYSROOT only when
one is needed. However, the change forgot that we require a sysroot
when a deployment target is requested. Teach Darwin.cmake to choose a
default CMAKE_OSX_SYSROOT when CMAKE_OSX_DEPLOYMENT_TARGET is set.

Cleanup in commit 9ed24c53 (FindSDL: Remove from find_... calls PATHS
that are set by default, 2012-09-04) accidentally dropped some search
paths. Restore the dropped PATH_SUFFIXES and add more suffixes needed
to search paths that were previously hard-coded.

The ComputePDBOutputDir added by commit 3f60dbf1 (Add
PDB_OUTPUT_DIRECTORY and PDB_NAME target properties, 2012-09-25) falls
back to the current binary directory instead of the target output
directory as before. When no PDB_OUTPUT_DIRECTORY property is set we
instead should fall back to the target output directory where .pdb files
used to go before the new property was added.
e386992 GexEx: Validate Target names and property names differently.
95d590d GenEx: Create cmGeneratorTargets for imported targets.
0442104 GenEx: Add an accessor for imported targets in a makefile.
We're going to need to link to them, and all the linking API is moving
to cmGeneratorTarget.
Skip imported targets when iterating over cmGeneratorTargets in places
where we only want targets we build. The GetGeneratorTargets result now
includes IMPORTED targets where it didn't before. The GetTargets
result, which was what used to be called in these methods does not
include IMPORTED targets. This doesn't relate to any known bugs, but in
some future uses of GetGeneratorTargets it will be important, so
starting the convention and being deliberate now is a good idea.
