# PMIX SEARCH_LIBS_CORE(func, list-of-libraries,

# added to the link command line for the static link case).
#
# NOTE: COMPONENTS SHOULD NOT USE THIS MACRO! Components should use
# PMIX_SEARCH_LIBS_COMPONENT. The reason why is because this macro
# calls PMIX_WRAPPER_FLAGS_ADD -- see big comment in
# pmix_setup_wrappers.m4 for an explanation of why this is bad).
