Crystal Window Theme

I was searching themes for my TDE install and found Crystal: http://kde-look.org/content/show.php/Crystal?content=13969 It's source so I tried to set it up but the configure script doesn't generate a Makefile. I get this error at the end: checking for KDE... configure: error: in the prefix, you've chosen, are no KDE headers installed. This will fail. So, check this please and use another prefix! I'm not sure what is being referred to by "KDE prefixes" nor how to fix it. I've been using TDE for a while and I'd like to contribute but I'm new to software engineering and I have no idea where to start when dealing with a project as big as TDE. But I would like to contribute by fixing this problem but I'm not sure how to go about it. Any help which can lead me in the right direction will be appreciated. Kai
