We're in the process of switching over to CMake for the Second Life viewer, and from what
we've seen so far, it looks great. When you have a lot of Windows and Mac programmers on your
team, it's a huge win for those people to be able to use the dev tools they are used to (e.g.
Visual Studio and XCode). The fact that CMake generates build files for those and a lot more
is a pretty unique characteristic among build systems.
