Title: Fix cmake

Those 3 commits about cmake was done by [davvid/partio](https://github.com/davvid/partio) and I have double checked to make sure it works well under Linux and Mac OS X. I like to suggest merge his work. Furthermore, that can make sure [mxcl/homebrew](https://github.com/mxcl/homebrew) will be happy to see that.
