Qt4Macros: Allow specifying a TARGET in invokations of macros.
That will allow things like this:
find_package(Qt4)
qt4_generate_moc(myfile.h moc_myfile.cpp TARGET foo) # Note, foo target doesn't
# exist until below.
add_library(foo ...)
The qt4_generate_moc call would use the INCLUDE_DIRECTORIES from
the foo target using generator expressions. Currently it reads
the INCLUDE_DIRECTORIES directory property, meaning that include_directories()
is required.
Support for the TARGET is also added to qt4_wrap_cpp, but not qt4_automoc,
as that is deprecated in favor of the AUTOMOC target property.
The moc tool reports failure if the Q_INTERFACES macro is used with
an argument which has not appeared with Q_DECLARE_INTERFACE, so that is
the basis of the unit test.
The command line arguments are now always written to a file, which is
passed to moc as the @atfile. This was already the case on Windows, but
now it is used everywhere. The reason for that is that it is not currently
possible to expand the list of includes from a target directly in
a add_custom_command invokation (though that may become possible in the
future). There is not a big disadvantage to using the file anyway on
unix, so having one code path instead of two is also a motivation.
