# Common Makefile for packages derived from the Netlib BLAS/LAPACK sources.
# Package Makefile sets LAPACK_COMPONENT and LAPACK_COMPONENT_CMAKE_ARGS to
# choose the library to install.
# LAPACK_COMPONENT can be "lapack", "lapacke", or "cblas",
# or any of those with 64 suffix for ILP64 mode (64 bit indexing).
