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 --inplace

Note that any other options supplied must come *after* --inplace
for it to take effect.

--static must come before --cppflags, --cflags, --cxxflags,
--libs and --gl-libs and --libs must come before the other ones.

wx-config can take optional argument that contains comma- or space-separated
list of wxWidgets libraries to compile and link against. This list can
include both core and contrib libraries. Special value "std" stands for all
libraries linked in by default. Examples: "wx-config --libs core,base"
or "wx-config --cxxflags core,base".

--gl-libs option is deprecated, use "--libs gl" instead.

If there are several different builds of wxWidgets installed in same prefix,
you can use --host, --toolkit, --unicode, --debug, --universal and --version
options to select one of them. Use --list option to show all available builds
that match given criteria.
