Dan just pointed out that it works if you have the correct $host-pkg-config
installed. I suggest changing
AC_PATH_TOOL([PKG_CONFIG], [pkg-config], [<something>], [$prefix/bin])
The problem is that if you want to use pkg-config only on, let's say, Linux,
then, when you cross-compile to WIndows, the present behavior is that if you
don't have the $host-pkg-config, if uses your Linux pkg-config which
inevitably becomes a problem.
I think that if $host != $build, you want to use only and only your
$host-pkg-config or you want all your PKG_CHECK... tests to quietly fail.
2 Eric: I prefer using AS_IF macro instead of shell if, it looks more
Thank you for the example
