I got a weird error in FindDCMTK.cmake after I changed the path where to build our MITK based app. The error originates from MITKConfig.cmake.in, where there is a comparison of two directory names by STREQUAL. Although, I used lower case drive letters everywhere, CMake turns the build directory names of external projects into a canonical form, in which the drive letters are upper case, and because of this the directory names will not match.

Pull request follows.
