We do not compile Fortran API and LAPACK by default. To customize build use the following vars: * OPENBLAS_TARGET (str) to force target * OPENBLAS_FORTRAN (YES) to build Fortran API * OPENBLAS_LAPACK (YES) to build lapack For example, $ ck install package:lib-openblas-0.2.19-universal --env.OPENBLAS_TARGET=ARMV7 --env.OPENBLAS_FORTRAN=YES --env.OPENBLAS_LAPACK=YES
