dnl @synopsis AC_INFINIBAND([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl This macro tries to find out how to compile programs that
dnl use the Infiniband ibverbs API.
dnl
dnl On success, it defines HAVE_INFINIBAND and sets INFINIBAND_LIBS
dnl to any libraries that are needed for linking
dnl Infiniband (e.g. -libverbs,...).
dnl
dnl If you want to compile everything with Portals, you should set:
dnl
dnl LIBS="$PTL_LIBS $LIBS"
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a Infiniband
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
dnl the default action will define HAVE_INFINIBAND.
