Installing Netcdf

I would like to write a fortran program which uses NetCDF. In order to do so, I have to have the netcdf-module somewhere on my harddisc, and tell my compiler where to find it. In Synaptic, the following packages are installed:
netcdf-bin
nco
netcdf-doc
libnetcdf-dev
libnetcdf6
libnetcdf-dev, especially, promises "everything needed for developing in C, C++, Fortran 77, and Fortran 90"; however, I cannot find the libraries anywhere on my system, and accordingly, I cannot develop anything. Where might the libraries be? They are neither in /usr/share, nor in /usr/lib. And how, in general, can I found out where a package installs its files on my machine?

If you open Synaptic and focus on any installed package then click "Properties" button, you can see dialog with "Installed Files" tab.
So netcdf libraries are in /usr/lib/ and include files in /usr/include if you installed libnetcdf-dev through packaging system
In addition to using system tools, nc-config and nf-config can help you find those details. This may be helpful if netcdf was compiled by you or someone else in your organization.
I believe nf-config only started shipping sometime after netcdf 4.2 was released, because the fortran lib was split into a different package then. So, if you fail to find the relevant fortran information with nc-config, check if nf-config exists somewhere and use it instead.
From netcdf 4.2 release notes:
Beginning with version 4.2, the three [c, c++, fortran] libraries are being released as separate packages.
Finally, here's a sample output of nc-config --all:
This netCDF 4.2.1.1 has been built with the following features:
--cc -> gcc
--cflags -> -I/usr/local/include -I/share/ed/local/spike/include
--libs -> -L/usr/local/lib -lnetcdf
--has-c++ -> no
--cxx ->
--has-c++4 -> yes
--cxx4 -> g++
--fc -> gfortran
--fflags -> -g -O2 -I/usr/local/include
--flibs -> -L/usr/local/lib -lnetcdff -lnetcdf -lnetcdf
--has-f90 -> yes
--has-dap -> yes
--has-nc2 -> yes
--has-nc4 -> yes
--has-hdf5 -> yes
--has-hdf4 -> no
--has-pnetcdf-> no
--has-szlib ->
--prefix -> /usr/local
--includedir-> /usr/local/include
--version -> netCDF 4.2.1.1
The left column has the options that can be sent to nc-config instead of --all to produce more specific output.
