[Dune] Problem linking with Pametis / GMP

[Sahai, Amal]

Hi 

I am trying to build dune with the following option file:

BUILDDIR=./
USE_CMAKE=yes
MAKE_FLAGS=-j4

CMAKE_PREFIX_PATH="/home/amal/LIB/parametis/parmetis-4.0.3-gcc-7.1.0-openmpi-2.1.1"

Despite setting the PARMETIS_ROOT and GMP_ROOT variables, the different modules are unable to detect parmetis. The CmakeCache.txt for dune-grid contains the following information:


//Include directory of ParMETIS
PARMETIS_INCLUDE_DIR:PATH=/home/amal/LIB/parametis/parmetis-4.0.3-gcc-7.1.0-openmpi-2.1.1/include

//Full path of the ParMETIS library
PARMETIS_LIBRARY:FILEPATH=ParMETIS_LIBRARY-NOTFOUND

//Name of the ParMETIS library (default: parmetis).
PARMETIS_LIB_NAME:STRING=parmetis

//No help, variable specified on the command line.
PARMETIS_ROOT:UNINITIALIZED=/home/amal/LIB/parametis/parmetis-4.0.3-gcc-7.1.0-openmpi-2.1.1


Also, the CMakeError.log contains the following message:

Determining if the include file parmetis.h exists failed with the following output:
Change Dir: /home/amal/LIB/dune/dune-project/dune-grid/CMakeFiles/CMakeTmp

I looked at FindParMETIS.cmake and "check_include_file(parmetis.h PARMETIS_FOUND)" fails, which results in  the "if(PARMETIS_FOUND)" not being executed. I don't understand why this is happening because looking at the value of PARMETIS_INCLUDE_DIR in CMakeCache.txt, cmake seems to have found the right include directory for Parmetis. The same issue occurs with regards to GMP for all modules that require these libraries.

I would be very grateful for any help in sorting this linking issue.
