# Wrapper around AC SEARCH_LIBS.  If a library ends up being added to
# $LIBS, then also add it to the wrapper LIBS list (so that it is
# 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).
