[Cmake] test target problems on Solaris 2.9

Since your subdirectory under source is called "test", make sees it and
thinks the "test" target is up to date (since there are no dependencies).
GNU make provides a ".PHONY:"  target that can be used to tell it to
ignore any file/dir called "test", but that isn't portable to other makes.
We're looking for work-arounds.  Any ideas?
