Config option​

Only ARPACK

-D USE_ARPACK:BOOL=ON

Both APRACK and PARPACK

-D USE_ARPACK:BOOL=ON -D USE_PARPACK:BOOL=ON

Build instruction for easifem​

Build only ARPACK

build_dir=$HOME/temp/easifem-extpkgs/arpack-ng/build/
cmake_def="-D CMAKE_INSTALL_PREFIX:PATH=${EASIFEM_EXTPKGS} -D BUILD_SHARED_LIBS:BOOL=ON -D CMAKE_BUILD_TYPE:STRING=Release -D MPI:BOOL=OFF"

cmake -S . -B ${build_dir} ${cmake_def}
cmake -B ${build_dir}
cmake --build ${build_dir} --target install

Build both ARPACK and PARPACK
