I will test it mith msvc express 2005.
After removing odbc32.lib odbccp32.lib in Windows-cl.cmake
(think this is a bug fix for cmake) cmake stops because of

-- kio/misc/kwalletd/ excluded from build, multiple definition of functions fromkwalletwizard.ui3
CMake Error: Could not find LibXml2
Could not find LibXslt
CMake Error: This project requires some variables to be set,
and cmake can not find them.
Please set the following variables:

Maybe it could use the zlib of cmake.
Any ideas?
