[Cmake] CMake string matching in an IF condition

[Bill Hoffman]

The NOT part will not work.

However, you can have an empty IF,
so it would be:

IF( ${allvxl_BUILD_DIR} MATCHES ${allvxl_SOURCE_DIR} )
ELSE( ${allvxl_BUILD_DIR} MATCHES ${allvxl_SOURCE_DIR} )
  INCLUDE( ${allvxl_BUILD_DIR}/CMakeListsLocal.txt OPTIONAL )
ENDIF
