The guide already contains information for use with Autotools.
Nowadays autoconf-archive contains additional macros for pkg-config
(don't list them all, because the list could change, just a link to the
autoconf-archive project should be enough).
Add also information about CMake and Meson.
In alphabetical order:
- Autotools
- CMake
- Meson
While PKG_PROG_PKG_CONFIG checks the version of pkg-config available at
build time, it doesn't check the version of the pkg-config macros being
used. PKG_PREREQ (like AC_PREREQ or LT_PREREQ) can be used to check the
version of the macros in use when configure is being generated by the
developer.

The pkg-config(1) manual includes a lot of details behind pkg-config,
but not the background and usage patterns. This guide tries to provide
users and developers with a starting point for pkg-config.
