At least for debugger_gdbmi_wx32_64.cbp and debugger_gdbmi_wx33_64.cbp, it might be better to pluralize the object_output reference as all other wx32_64.cbp and wx33_64.cbp files do. For instance, change <Option object_output="../../../.obj33_64/plugins/contrib/debugger_gdbmi" />
to <Option object_output="../../../.objs33_64/plugins/contrib/debugger_gdbmi" />
in the file debugger_gdbmi_wx33_64.cbp
