This doesn't answer my question. 
Why is it helpful to know the location of the Windows-DLL during the
build-process? 
I'm not an expert, but for me it makes only sense, if I want to use a
DLL, which is not located in an execution-directory of the OS. 
This would a nice feature.

No, without http://www.cmake.org/Wiki/CMake_2.6_Notes
you are helpless.

Who needs this?

Anyway, thanks for help.
