To skip this feature and # look for a stand alone lapacke, please add the following in your # CMakeLists.txt before to call find_package(LAPACKE): # set(LAPACKE_STANDALONE TRUE) #============================================================================= # Copyright 2012-2013 Inria # Copyright 2012-2013 Emmanuel Agullo # Copyright 2012-2013 Mathieu Faverge # Copyright 2012 Cedric Castagnede # Copyright 2013-2016 Florent Pruvost # # This file is part of a computer program whose purpose is to process # Matrices Over Runtime Systems @ Exascale (MORSE).
