# A word of explanation...
#
# This library is linked against various MCA components because all
# shared-memory based components (e.g., mpool, ptl, etc.)  need to
# share some common code and data.  There's two cases:
#
# 1. libmca_common_portals.la is a shared library.  By linking that shared
# library to all components that need it, the OS linker will
# automatically load it into the process as necessary, and there will
# only be one copy (i.e., all the components will share *one* copy of
# the code and data).
# 2. libmca_common_portals.la is a static library.  In this case, it
# will be rolled up into the top-level libmpi.la.  It will also be
# rolled into each component, but then the component will also be
# rolled up into the upper-level libmpi.la.  Libtool sorts this all
# out and it all works out in the end.
#
# Note that building this common component statically and linking
# against other dynamic components is *not* supported!
