Is plugin_LTLIBRARIES a buildin variable like lib_LTLIBRARIES and noinst_LTLIBRARIES?

Recently I read the source code of strongswan. And I found this piece of script in one Makefile.am. I didn't see plugin_LTLIBRARIES before. I searched on the internet. Most of the result is Makefile.am files. Is is a M4 macro or a buildin variable? What's the usage of it?

if MONOLITHIC
noinst_LTLIBRARIES = libstrongswan-socket-default.la
else
plugin_LTLIBRARIES = libstrongswan-socket-default.la
endif

Any automake variable of the form foo_PRIMARY installs to $(foodir). $(plugindir) might be set via AC_SUBST in configure.ac.

m4 isn't used in handling Makefile.am. They're parsed with automake, a perl program, because the logic involved in building the Makefile.in template is much more subtle than straight macro expansion.
