use Requires.private if pkg-config is sufficiently recent. We do this:

in configure.ac:

if $PKG_CONFIG --atleast-pkgconfig-version 0.22; then
   pkgconfig_requires_private="Requires.private"
else
   pkgconfig_requires_private="Requires"
fi
AC_SUBST(pkgconfig_requires_private)

in the .pc.in file:

@pkgconfig_requires_private@: @requirement@

(where requirements is an AC_SUBST'ed variable containing the needed
dependencies)
