# Autotools has some unfortunate issues with library handling.  In order to
# get a server to rebuild when a dependency in the tree is changed, it must
# be listed in SERVERNAME_DEPENDENCIES.  However, no system libraries may be
# listed there, or some versions of autotools will break (especially if a -L
# is required to find the library).  So, we keep two sets of libraries
# detected: NAMESPACE_LIBS for in-tree libraries to be linked against, which
# will go into the _DEPENDENCIES and _LDADD of the server, and
# NAMESPACE_SYS_LIBS which will go into only the _LDADD.  The
# NAMESPACEMODULES_LIBS detected from pkgconfig should always go in
# NAMESPACE_SYS_LIBS.
#
# XSERVER_LIBS is the set of in-tree libraries which all servers require.
# XSERVER_SYS_LIBS is the set of out-of-tree libraries which all servers
