34 dnl installed version of pkg-config, this checks the developer's version
35 dnl of pkg.m4 when generating configure.
36 dnl
37 dnl To ensure that this macro is defined, also add:
38 dnl m4_ifndef([PKG_PREREQ],
39 dnl [m4_fatal([must install pkg-config 0.29 or later before running autoconf/autogen])])

42 dnl of the macros you require.

55 dnl is at least MIN-VERSION. If MIN-VERSION is not specified, 0.9.0 is
56 dnl used since that's the first version where most current features of
57 dnl pkg-config existed.
