The 'rcc --list' operation may print newlines of the form CRCRLF,
so strip any trailing CR characters found on each line.
Update the Tests/QtAutogen test to use a resource named in a
subdirectory. This causes 'rcc --list' to display a blank line
and tests that it is correctly filtered out.
Get dependencies from the output of ``rcc --list`` if using
Qt 5. Otherwise process the file in the same way as the
qt4_add_resources macro.
This does not work for RCC files which are generated.
The cmake_autogen build step is implemented as a PRE_BUILD step
of the target currently if possible, rather than a standalone
custom target. This is to keep the number of (synthesized)
custom targets that appear in the UI low, but in some cases
it is necessary to fall back to a full custom target.
Fall back to a full custom target for the VS builds if autorcc
is used.
