Compiling QGIS (with customizations) for Windows

Question

I was able to customize a few features of QGIS in Ubuntu. Now I am trying to compile the same code on Windows, by following the installation guide given for Windows. I have downloaded all of the dependencies using OsGeo4W and struck at SIP. I tried setting environment variables to point to sip site-pacakges too ( C:\OSGeo4W\apps\Python27\lib\site-packages ) I am using visual studio compiler libraries.

Here is the cmake trace

Try using the python shipped with OSGeo4W. You might find the cmake call in ms-windows/osgeo4w/package.cmd useful - it contains all the options used for the OSGeo4W qgis build.
