Issue with installing Catalyst with external conduit

I am trying to install Catalyst agains the external conduit installation but getting error like following,

The cmake command that I am using is,

cmake -DCMAKE_INSTALL_PREFIX:PATH=/glade/work/turuncu/COP/catalyst/install -DCMAKE_BUILD_TYPE=Release -DCATALYST_WITH_EXTERNAL_CONDUIT=ON -DConduit_DIR:PATH=/glade/work/turuncu/COP/conduit-0.8.8/install/lib/cmake/conduit -DCATALYST_USE_MPI=ON -DCATALYST_WRAP_FORTRAN=ON -DCATALYST_WRAP_PYTHON=ON ../

BTW, I am using v2.0.0-rc4. tag for Catalyst and 0.8.8 for Conduit. If I use internal Conduit, I could able to compile Catalyst without any issue (I did not test the installation yet).
