RFC Implement CMake build

This patch adds a mostly complete (aside from building tests, documentation, installation, etc.) CMake build to the git project. I am not sure how much interest there is in a CMake build, so please send me feedback one way or another. Personally, I believe CMake will help with Windows builds and is somewhat easier to read than a Makefile. I considered, adding this to the contrib directory, but CMakeLists.txt almost always reside in the original directories, and I'm not sure how wise it would be to do otherwise. If you are interested in a CMake build, I would be more than happy to finish up the work here. Decided to wait until I discussed the issue here to finish the final parts of the build.
