If the source has #include "dcmtk/config/osconfig.h" then it will not 
help you to have ${prefix}/include/dcmtk/config in the search path, you 
need to have ${prefix}/include.

That's probably a bit strong.

Why don't you try some modern printf-style debugging? :-) Modify the 
FindDCMTK.cmake file with some message(...) calls and see what is going on?

I use FindDCMTK.cmake, but I use it against an installation directory 
nor against a source directory. The installation directory is created by 
dcmtk when building the install target. I use the cmake tool chain for 
dcmtk as well. The macro is supposed to work against both source and 
installation trees.
