CMAKE_CXX_LINK_EXECUTABLE with LINK as an adjective - specify the
executable that does linking - whereas the above use of CREATE makes
clear that the sense of LINK is intended to be as a verb - specify how
to create an executable. The docs did say that this variable specifies a
rule, now that I know what to look for.
