[CMake] Transfer Kdevelop-managed project to cmake with .ui files and generated ui_*.h

[junior0007]

Hey Guys,

I have a nice little project running (so far) under Kdevelop that
contains some .ui-files. So far these ui-files are compiled using uic (i
guess... - it's autom. done by Kdevelop...) so that the result is an
ui_*.h file. This ui_*.h File is then included by the classes.

So far i already found some nice help browsing this list and so i might
be on the right way. However i still have linking-probs maybe you can
help.

The Project tree looks like:
  > project
    > bin
    > src
      > gui
      > gui_ui
      > model

So far i just put a CMakeLists.txt into the project und project/src -
directory and startet with trial-and error - lots of errors

I already had a look at the list and found some things that should do
the work, but how?

Here is the src/CMakeLists.txt:

Works nice until linking... Linking causes: undefined reference to

Can anybody help?
