I've adjusted your CMakeLists.txt to use
set_source_files_properties(${QTCMake_SRC} PROPERTIES OBJECT_DEPENDS
"${UIHeaders}")
The generated Makefiles do generate the headers from the ui files before
building the object file for the executable. So this does work as long
as you're using quotes around the variable. It also works that after
touching a .ui file the header gets re-generated. (I'm using CMake 2.8.1
currently here).

It does make sure that _something_ depends on the generated header
files. This then triggers generating them from the .ui file. I think
thats the problem with your original example, there's nothing (in
particular no target) that depends explicitly on the generated header
files and hence the "all" target doesn't generate them.
This is pretty similar to your approach with
set_source_files_properties, except its a bit more hidden whats going on
and the dependency is probably between the target and the header.
