Why is IF("${VARIABLE}" MATCHES "^${VARIABLE}$") used instead of IF( ${VARIABLE} STREQUAL ${VARIABLE} ) (which would always return true)? I'm not sure of use case but I'd say it's checking for special characters in VARIABLE.If it's checking for special characters then I have to say that it's not the right way. For example, if VARIABLE == "a/b" then the IF statement is still TRUE.
It is checking to see if the VARIABLE has a value at all. It is old code before we had IF(DEFINED VARIABLE) but works with all versions of CMake.
