With Open MPI 5.0, the decision was made to stop building 3rd-party packages, such as Libevent, HWLOC, PMIx, and PRRTE as MCA components and instead 1) start relying on external libraries whenever possible and 2) Open MPI builds the 3rd party libraries (if needed) as independent libraries, rather than linked into libopen-pal. This patch is the first step in that process, providing foundational changes required for supporting 3rd-party packages, such as changes to autogen.pl, the top-level Makefile.am, and introducing two Autoconf macros to support running sub-configure scripts; one supporting source in tarball form and the other supporting source in a sub-tree.

dnl
|
|
dnl The subconfigure argument list is created based on "ac_precious_vars"
|
|
dnl instead of explicitly use of well-known Makefile variables, like
|
|
dnl CC/CFLAGS/CPPFLAGS..., this generalization is effective as long as
|
|
dnl calling configure.ac declares the needed variables to be passed down
|
|
dnl to subconfigure as "precious" appropriately. The precious variable
|
|
dnl can be created in the following ways:
|
|
dnl 1) implicit declaration through use of autoconf macros, like
|
|
dnl AC_PROG_CC (declares CC/CFLAGS/CPPFLAGS/LIBS/LDFLAGS), or
|
|
dnl AC_PROG_F77 (declares F77/FFLAGS/FLIBS) ...
|
|
dnl which are in turns invoked by other subconfigure.
|
|
dnl When in doubt, check "ac_precious_var" in the calling configure.
|
|
dnl 2) explicit "precious" declaration through AC_ARG_VAR.
|
|
dnl Without correct "precious" declaration in the calling configure.ac,
|
|
dnl there would be variables not being included in the subconfigure
|
|
dnl argument list.
