Discussion related to cado-nfs

["Thomas D. Dean" <tomdean@wavecable.com>]

I restarted cado-nfs. It failed in sqrt.

Warning: dependency 40 does not exist, reducing the number of threads to 0

Question: If I zap the entire cado-nfs directory and clone again. Then,
mkdir build
cd build
cmake ..
How can I tell if local.sh is included by cmake?
