Now, under Debian 10+ and Ubuntu 18.04+, we link against the GTK-3 version of wxWidgets (libwxgtk3.0-gtk3-0v5).
Under Debian 9- and Ubuntu 16.04, we link against the GTK-2 version of wxWidgets (libwxgtk3.0-0v5) which is the
only one available.
Also, we now have 2 separate RPM scripts : 'build_cmake_rpm_gtk2.sh' which builds wxWidgets and links it against GTK-2,
then links VeraCrypt against 'gtk2' package (typically to be used under CentOS 6) and 'build_cmake_rpm_gtk3' which builds
wxWidgets and links it against GTK-3, then links VeraCrypt against 'gtk3' package (typically to be used under CentOS 7+).
