kde headers

[Andrew Zaenglein]

when i try to install themes/window decorations/etc. i get the error  
message:

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!



so my question is: how do i install the KDE headers?  or more  
generally, how do i install any kid of headers?







i didn't install them initially.  i didn't know how handy they would  
be.

any help at all would be very much appreciated,
