[Dune] Building DUNE with Cmake: SuperLU

[lriedel at iup.uni-heidelberg.de]

Dear Dune Developers,

when switching from the Autotools buildsystem to CMake, I encounter the
problem that the SuperLU package is found but the respective Linear Solver
in the dune-istl package cannot be used.
Using Autotools, I needed to add the SuperLU LIBS, LDFLAGS and CPPFLAGS to
the respective Makefile.am of the project and it would work fine. Do I
need to do something similar when using CMake?

With Autotools I execute

$ ./dune-common/bin/dunecontrol --module=<myproject> --opts=config.opts all

with the opts file containing

 CONFIGURE_FLAGS=" --enable-parallel
--with-superlu=$INSTALLDIR/SuperLU_4.3
--with-superlu-lib=libsuperlu_4.3.a
--with-blas=$INSTALLDIR/OpenBLAS/lib/libopenblas.a <...>"

Switching to CMake I execute

$ ./dune-common/bin/dunecontrol --use-cmake --module=<myproject>
--opts=config.opts all

with the opts file containing

 CMAKE_FLAGS="-DUSE_MPI=ON -DSUPERLU_ROOT=$INSTALLDIR/SuperLU_4.3
-DBLAS_ROOT=$INSTALLDIR/OpenBLAS/lib/libopenblas.a <...>"

Partial output of configure:

But when compiling the project, I receive the error
 error: 'ISTLBackend_SEQ_SuperLU' in namespace 'Dune::PDELab' does not
name a type
   typedef Dune::PDELab::ISTLBackend_SEQ_SuperLU LS;

Do I need to add something specific to the CMAkeLists.txt files?

Thank you in advance and best regards,
