Undefined Symbol Error When Making

[bcaddy]

cnpy builds just fine when I link it to my project I get the following error

/usr/local/bin/g++-11 -std=c++17 -Wall -Wextra -Wpedantic -g -O0  -fopenmp src/rw-main.cpp -o  bin/rw-main.exe -I/Users/Bob/Desktop/cnpy -L/Users/Bob/Desktop/cnpy/build -lcnpy -lz

I'm trying to install and build it in cnpy/build since I don't have permission to install in the standard locations on the clusters I use
