It seems fairly obvious how they're defined from that.
Usually custom options would be activated with -d and tested for with if
BUILD_SHARED_LIBS in particular
alters the behaviour of add_library
defined (via any means).
ie. add_library(name STATIC sources...) will always build a static library.
add_library(name SHARED sources...) will always build a shared library.
add_library(name sources...) will build a shared library if
BUILD_SHARED_LIBS is ON, otherwise a static library.
This information was not hard to find.
