CMAKE_SOURCE_DIR is the value of the top level source tree that you
give to cmake (or cmake-gui, or ccmake) when you configure a build
tree.

CMAKE_CURRENT_SOURCE_DIR starts out as CMAKE_SOURCE_DIR in the top
level CMakeLists.txt file, and then changes value as subdirectories
are traversed via add_subdirectory.
