The alternative is

SYSTEM_TOOLS( GET_PATH varname fullpathname)

which would allow for a few system type commands to be placed
together, but .. the problem is that all cmake commands can be
expressed as

SYSTEM_TOOLS( cmd args args args...)

so where do you draw the line. I'd probably stick with GET_FILEPATH
since it is more consistent with the other commands and I can't think
of too many system commands that would be used.
