我想构建成cppm里声明导出模块和接口，定义实现内容放在.cpp文件里：

module;

#include <BinDrivers.hxx>
#include <BinDrivers_Marker.hxx>
#include <BinLDrivers_Marker.hxx>

export module occ_module.application_framework.tkbin;

export namespace occ_module {
using BinDrivers = ::BinDrivers;
using BinDrivers_Marker = ::BinDrivers_Marker;
}
