とりあえず、Pythonバインディングは作らない。

source ~/rokko/scalapack/scalapack-2.2.0-2/Debug/scalapackvars.sh

ビルドに使うコマンド

cmake ~/development/rokko -DCMAKE_CXX_COMPILER=mpicxx -DCMAKE_C_COMPILER=mpicc -DCMAKE_Fortran_COMPILER=mpif90 -DCMAKE_BUILD_TYPE=Debug -DBUILD_BENCHMARKS=ON -DCMAKE_INSTALL_PREFIX=~/rokko/rokko -DBUILD_Python_BINDING=OFF -DLAPACK_LIBRARIES="-Wl,-framework -Wl,Accelerate" -DBLAS_LIBRARIES="-Wl,-framework -Wl,Accelerate"
