/*
Some (but not all) mkl functions require openmp, but Intel does not add these
to SO_NEEDED and instructs users to put openmp on their LD_LIBRARY_PATH. If
you are using mkl and your library/application is using some of the functions
that require openmp, add a setupHook like this to your package:
setupHook = writeText "setup-hook.sh" ''
addOpenmp() {
addToSearchPath LD_LIBRARY_PATH ${openmp}/lib
}
addEnvHooks "$targetOffset" addOpenmp
'';
We do not add the setup hook here, because avoiding it allows this large
package to be a fixed-output derivation with better cache efficiency.
