Since the file containing "INCLUDE_DIRECTORY(.)" is in directory
${CMAKE_CURRENT_SOURCE_DIR} , I would never translate that to
${CMAKE_CURRENT_BINARY_DIR}.
"." means "The directory where I am", where "I" refers to the one speaking,
in this case the CMakeLists.txt file.

No, indeed.  It probably makes little sense to pass "." to
INCLUDE_DIRECTORIES (although it could), but it could make a lot of sense
to e.g. pass it to ADD_TEST, i.e., as command line argument to executables.
Or as part of the argument of an INCLUDE.
