Hi Maciej

In the latest nightlies they are now stored in lib/ngspice/

I guess that should equate to a relative path to the executables to
../lib/ngspice/*.cm, given that the exe's are in the bin folder on the
same level as lib.

So feel free to submit your fix. Also, are there any demos that make
use of those cm libs such that it can be tested?

Nick
