Components explained

Through this documentation you will come across 'components' a bunch, here's the deal.

A 'component' is a single self-contained part of the project. This may be a cursor theme, icon theme, library, program, or whatever. Each one of these is a component.

Each one lives in its own directory, with a CMakeLists.txt at the root that defines the CMake project. The most simple one being the Build Tag, under /base/bldtag - it only consists of the CMake project itself.
