Is this just for one image ?

Yes, you need add_custom_command(), if it's for more than one image you should 
put it in a macro, something like this:

macro(embed_images src img)
  add_custom_command(OUTPUT ${src}
                     COMMAND ${QT_UIC...} ...
                     DEPENDS ${img} )
endmacro(embed_images src img)


embed_images("${CMAKE_CURRENT_BINARY_DIR}/image.cpp"  about.png)
add_executable(foo file1.cpp ... "${CMAKE_CURRENT_BINARY_DIR}/image.cpp")

If it's more than one image you can also put this in a foreach() loop inside 
the macro.

If you have that working, it would be nice if you could post the script here.
