It sounds like you do not propagate the environment when calling
setenv.bat from python. There is an option to do so in
subprocess.Popen init method, or you can define your own environment
if you do not want to propagate the whole environment (but this is
often difficult to avoid for build environment in my experience,
expecially if you don't have access to the sources of the whole system
to check which variables are necessary).
