I did not found a "ready to used" cmake script, so I suggest to run the
following simple python script from cmake, which checks, if a python
module is loadable.
cat cmake/check_python_module.py
----------------------------------------
import imp,sys
try:
imp.find_module(sys.argv[1])
exit(0)
except ImportError:
exit(1)
----------------------------------------
Run that script by cmake with
python cmake/check_python_module.py xrld
and check the exit code 0 - found, 1 - not found.
Additional the file README.md should get the new dependency listed e.g.
installed python modules: ctypes, sqlite3, xlrd >= 0.7.1

Ralf
