Any instruction for building from source?

[Timtaran]

Recently, I tried to build the project and gain at least some understanding of the source code. I don’t see any build instructions, so I’m following the original PSMS "Building from Source". Here are the issues I’ve encountered (apologies in advance for my inexperience, if that's the case):

1. CMake cannot retrieve version from ProtocolVersion.h
2. Kalman filters deleted in 3f94ab4, but there is still in tests and CMakeLists.txt
3. roject fails to build with 60+ errors. Most of them says ButtonChecked found in ImGui (I failed to find any info about it in google).

The project is currently not buildable as this whole project needs some proper cleanup and uploaded changed modules (Such as ImGui and PS3EYEDriver). Will happen some day in the future when i got some time. The original PSMoveService building instructions are pseudo, so C++ knowledge is required.
