compiling LyX 2 on windows

[Janwillem van Dijk]

I successfully compiled Lyx on Linux (ubuntu 9.10 X86 and 9.04 AMD64) 
but fail to get it done on WinXP. Having no compile experience in 
windows I cannot find how to get around the error that windows.h cannot 
be found. I installed the windows sdk and visualc packages. There is 
windows.h in the PATH and I even copied it to c:\ but the problem 
remains. Please help me!
thanks, Janwillem
