Usage: wx-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--release]

                 [--cc] [--cxx] [--ld]

wx-config returns configuration information about the installed
version of wxWidgets. 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 wxWidgets 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.

--static must come before --libs and --gl-libs.

--libs can take optional argument that contains comma-separated list of
wxWidgets libraries to link against. This list can include both core
and contrib libraries.

--gl-libs option is deprecated, used --libs=gl instead.

    # the ANSI-fied versions of them in its private directory which is searched
    # after all the directories on the cmd line.
    #
    # the situation is a bit more complicated with -I/usr/local/include:
