Does that become something like a "put anything into the source list"? I 
thought about something like this:

add_executable(foo foo.cpp foo.h foo.ui main.cpp junk.xml)

And in CMake there is a set of filters that can be enabled by properties (like 
the AUTOMOC) one.

Something like this

filter_cpp() -> add to compiler inputs
filter_automoc() -> the automoc stuff
filter_header() -> just mark as used
filter_ui() -> uic
filter_rcc() -> qrc
filter_res() -> add to linker inputs on Windows, just mark as used on other 
platforms

The junk.xml file is not accepted by any filter, so it would raise an error as 
"unknown source file".

It would become extremely useful if such filters could be added by CMake code. 
Think of KDE just adding a filter for kcfg files so they could just be added to 
the targets as an ordinary source file.

Greeting,

Eike
