Remove use of an old hack that takes advantage of the auto-dereference behavior of the if() command to detect if a variable is defined. The hack has the form: if("${VAR} MATCHES "^${VAR}$") where "${VAR}" is a macro argument reference. Use if(DEFINED) instead. This also avoids warnings for CMake Policy CMP0054 in CMake 3.1.
