[CMake] cmake Qt4 and uic3

[Kelly Burkhart]

Hello, I'm in the process of converting our build system from qmake to
cmake.  We have a number of projects that use uic3 rather than uic and
I'm having a difficult time figuring out how to run the older command.

I've tried copying QT4_WRAP_UI to a differently named macro and
changing the 'COMMAND ${QT_UIC_EXECUTABLE}' line to: 'COMMAND
${QT_UIC3_EXECUTABLE}' with no luck.

As I continue to dig into this has anyone else come up with a recipe
for doing this?

Thanks,

-Kelly
