By richardkchapman:

Not sure exactly what the scope of this symbol is in CMake, but it's not particularly well named.

I think I would have done it without using an extra symbol at all, i.e. move this code down a bit and say

```
IF (USE_XALAN)
set (SRCS ${SRCS} xalan_processor.cpp xerces_validator.cpp)

etc
