Hi Mary:
I am not a pip expert but what I know is:
pip is just executing your setup.py, what I do for one of my projects is:
add a call to make and package the Makefile...(
https://github.com/guziy/pylibrmn/blob/master/setup.py)
There is a package netcdf4-python on github, it depends on hdf5 and netcdf
and just checks if those 2 are installed either by looking at env variables
HDF5_DIR, NETCDF4_DIR, or using config utilities nc-config ....
https://github.com/Unidata/netcdf4-python
What I would do is just list those dependencies, and the way they are
supposed to be built, compiler versions and flags, and install only
wrappers and python codes using pip...
Cheers
