 The PDAF library, thus the core routines of PDAF and PDAF-OMI, can also be compiled separately. This is the common approach when one implements PDAF with some models in the online-coupled setup (see e.g. the directory `modelbindings`).

+To point to the PDAF include directory to ensure that `pdaf_interface_module` and the `PDAFomi` module are found, one should specificy
+{{{
+   -I${PDAFROOT}/include
+}}}
+Here `${PDAFROOT}` is the directory of the PDAF package. It can either be directly specified by replacing ${PDAFROOT} or one speficies PDAFROOT as a variable.
+
+For linking the PDAF library for the ensemble schemes use
+{{{
+   -L${PDAFROOT}/lib -lpdaf-d
+}}}
+while in case of the PDAF library supporting the 3D-Var schemes use
+{{{
+   -L${PDAFROOT}/lib -lpdaf-var
+}}}
+
+Apart from the PDAF library, one also needs to specify the location of the BLAS and LAPACK libraries (for example by setting `-lblas -llapack` if the libraries are installed in standard directories)
