dnl ---------- AC_PROG_SGPEMV2 ---------------------
dnl
dnl Synopsis: AC_PROG_SGPEMV2([min_version])
dnl
dnl This macro checks if sgpemv2 is installed, and
dnl AC_SUBSTs the following variables:
dnl
dnl SGPEMV2_CFLAGS -> necessary includes for compiling
dnl plugins
dnl SGPEMV2_LIBS -> libraries to link against when
dnl building a loadable plugin
dnl SGPEMV2_POLICIES_DIR -> global policies directory
dnl SGPEMV2_PLUGINS_DIR -> global plugins directory
dnl
dnl This is particularly useful for plugin installation.
dnl It takes a parameter which is the minimal version
dnl installed of sgpemv2 this macro checks for.
dnl The parameter is mandatory.
dnl
dnl Example of usage: AC_PROG_SGPEMV2([0.1])
