Code review comment for lp:~canonical-platform-qa/url-dispatcher/fake_dispatcher

The problem is CTest sucks, so I've not been able to figure out either how to set the environment (the setting seems to take effect only during the actual execution of cmake), or set the PATH in the test command - CTest automatically thinks the first word in the add_test line is a command. The .in substitution could work, maybe - but that might depend on getting these files copied into the build directory, which I've had no success with so far.
