Oh please no. Env vars work great under Unix but dealing with them
under Windows is like pulling teeth. You could not set one env var
anyway since each subdir is going to need its own srcdir. That is why
you need a different srcdir file in each subdirectory in the build dir.

For example, assume you root srcdir was /tmp/src/foo and you were running
in /tmp/build/foo/one and /tmp/build/foo/tmp. You would need to set
the var to /tmp/src/foo/one and then run the first test. You would then need
to set the var to /tmp/src/foo/tmp and run the second test. It would just be
a big pain since you would also need to pass the fully qualified path of the
python script on the command line:

cd /tmp/build/foo/one
setenv SRCDIR /tmp/src/foo/one
python /tmp/src/foo/one/test.python

Yuck, right?
