I have CMake, version 3.0.1.
CMAKE_BUILD_TYPE is not defined.

WARNING: CMAKE_BUILD_TYPE is not defined!

There is no issue here. All the message is telling you is that you haven't manually set a CMAKE_BUILD_TYPE, so it's using the default (RelWithDebInfo, a release build including limited debug info).

Why CMake is asking for ENet (already in source)?

I didn't edit CMake (I'm not using it).
It uses Enet from repos. Which is the best solution for any GNU/Linux.
While the VC project uses the included sources (so its easier to build on Windows).
