This is by far better than misusing cmake as it is done now. This is hard to 
understand and will probably lead to hard-to-trace problems. 
For the only two options we have see below.

I see only these two options:

1) put the functions which are provided by kdewin32 in 
ConfigureChecksWin.cmake and everything should work smoothly in one go

2) compile kdelibs/win/ completely separate from kdelibs/.
I.e. 
-run cmake in kdelibs/win/CMakeLists.txt
-compile and *install* kdelibs/win/
-run cmake in kdelibs/, ignore kdelibs/win/ completely, check for the 
availability of the kdewin32 library as usual.

Since option 2) requires more changes in the source code, like adjusting 
kdemacros.h etc., I vote strongly for option one for now. This way we will 
have a smoothly working cmake build on windows very soon.

So, Peter, can you please change it back the all-in-one-go style, using 
COnfigureChecksWin.cmake ?

Bye
Alex
