cmake conversion #1

I've added a man page taken from your Debian packaging system.

Please, give attention to my comments below. For now, I did not test it but it looks good.

So many change in the cmake modules, I get lost.
Feel free to add/change anything, I won't work on kshudown anymore.

Okay, that's no problem. Changes in the common cmake module are not large and most represent simplification for individual projects. I'll finish it.

   set( __KDE_HAVE_GCC_VISIBILITY 1 )
   set( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fvisibility=hidden -fvisibility-inlines-hidden")
   set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fvisibility=hidden -fvisibility-inlines-hidden")
 endif( WITH_GCC_VISIBILITY )

   if( NOT MSGFMT_EXECUTABLE )
     tde_message_fatal( "msgfmt is required but was not found on your system." )
   endif( NOT MSGFMT_EXECUTABLE )
 endif( BUILD_TRANSLATIONS )
