wx-config returns configuration information about the installed
version of wxWindows. It may be used to query its version and
installation directories and also retrieve the C and C++ compilers
and linker which were used for its building and the corresponding
flags.

Ordinarily it should be installed to the appropriate system location
along with the headers and library files, but it is also possible to
use it to enable builds with an uninstalled wxWindows version for
package building and bleeding edge developers.  To do so, use it like
this:

\${wx_builddir}/wx-config --prefix=\${wx_srcdir} --exec-prefix=\${wx_builddir}

Note that any other options supplied must come *after* the prefix
specification for it to take effect.
