As you can see in your list, the main wxWidgets library (as well as the Open GL one) is not there. For the static monolithic release build, the files in the lib folder should be
libwxexpat.a
libwxjpeg.a
libwxmsw30u.a
libwxmsw30u_gl.a
libwxpng.a
libwxregexu.a
libwxscintilla.a
libwxtiff.a
libwxzlib.a
You need to take a look at the build output, the last messages there in particular.
If you really used only the command you posted above, that usually does not work. If you want to use parallel bulds with gcc, you need to
build the setup_h target first.
But there can be other issue, the only way to know is checking the build output...
