On windows I have several completely separate build trees with their own environment. This way I can build for different compiler versions, 32/64 bit and different versions of libraries like this. Inside the root of each build tree there is a link to the appropriate Visual Studio command prompt that has its default folder set to the build tree root. Also in the root there is a batch file that sets quite a few _DIR environment variables to help cmake find the correct compiled libraries. This has worked well for the 5 or so years that I have done it this way. I do not use INSTALL targets so none of the binaries end up in Program Files.
