Of course.  And on Windows kdewin package is required too.
I was planning to add another page where I list the stuff
required for building anything KDE.

Right.  So one I idea I have is to process all the modules together and do
some kind of factoring of all the packages needed.  Then make another page
listing all the packages and in what modules they are needed.

On my todo list.

Well, I'm not planning to write a CMakeLists.txt parser.
So I'm not planning to handle CMake conditionals.
But I can add hacks as needed. 

In the case of QtDeclarative, the comment says that it is needed for Mobile.
Making sure we have useful comments and descriptions can certainly help too.
