Ryppl/cmake integration making progress

Lately, we’ve been working on getting ryppl to play nicely with CMake. That is, we want ryppl to automatically detect that a package is CMake-able and invoke appropriate cmake commands to do things like build and install. I’m happy to say that for simple projects, that now works. If you use CMake’s built-in install macro to install files, then ryppl will just do the right thing. What’s more, we can take the output of CMake’s install command to automatically generate the project’s manifest so that ryppl knows how to uninstall it. Neat and tidy.
