42dnl PKG_PREREQ(MIN-VERSION)
43dnl -----------------------
44dnl Since: 0.29
45dnl
46dnl Verify that the version of the pkg-config macros are at least

48dnl installed version of pkg-config, this checks the developer's version
49dnl of pkg.m4 when generating configure.
50dnl
51dnl To ensure that this macro is defined, also add:
52dnl m4_ifndef([PKG_PREREQ],
53dnl     [m4_fatal([must install pkg-config 0.29 or later before running autoconf/autogen])])

56dnl of the macros you require.
