Status with Netcdf

In previous installations one did set path to netcdf as listed next

NETCDFHOME=/usr/lib
NETCDF_PREFIX=$NETCDFHOME

But reading the BUILDING.md file, it mentions only the path to gmt.

export PATH=${PATH}:/path/to/gmt/bin

Does this mean that users no longer have to define the netcdf path when setting gmt?

I do not approve bothering users with netcdf paths as the procedure is not straight-forward.
