A possible solution is using flags in the cabal configuration file. For
instance, I have this in hmatrix.cabal:
extra-libraries: gsl mkl_lapack mkl_intel_lp64 mkl_sequential mkl_core
extra-libraries: gsl mkl_lapack mkl_intel mkl_sequential mkl_core
extra-libraries: gsl blas lapack
so if I want to link with Intel's MKL optimized blas/lapack instead of
ATLAS I simply add the -fmkl flag:
runhaskell Setup.lhs configure -fmkl etc.
cabal install hmatrix -fmkl
Other flags can be added to support different distributions. We could
have something like
cabal install package -ffedora
cabal install package -fcblas
