I think you misuse some CMake directive, keep reading...

This previous one is wrong, link_directories is seldom used for your
own library.
The forthcoming
target_link_libraries (mymain Hydro)
is enough for CMake to find how to link "mymain" to "Hydro" lib.
Try removing this "link_directories" line.

This statement looks wrong as well
NETCDF_INC must a path to an include directory not a path
to a library?
What you probably need is
target_link_libraries (mymain Hydro $(NETCDF_LIBRARY) )
with NETCDF_LIBRARY being the full path to the NETCDF library.
