It is much easier if you use GNU Automake instead of writing your own
Makefiles. If you do that you do not have to worry about finding and
invoking the @command{pkg-config} script at all. @acronym{GPGME}
provides an extension to Automake that does all the work for you.
You can simply use @code{PKG_CHECK_MODULES} macro with @command{pkg-config}:
@example
PKG_CHECK_MODULES([GPGME], [gpgme >= 1.23.1])
@end example
Alternatively, instead of using @command{pkg-config}, for building on
an environment with no pkg-config, @acronym{GPGME} provides an
extension to Automake that does all the work for you. Please note
that it is required to have gpgrt-config from libgpg-error installed
in this case.
@c A simple macro for optional variables.
@macro ovar{varname}
