软件包中有完整CMakelists.txt

如上是示例，这种类型比较简单，包含了cmake.mk后，openwrt会自动生成编译，只需要安装需要被其他代码依赖的库和头文件，以及运行时需要的库即可。

软件包中有完整CMakelists.txt但需要创建build目录

include $(TOPDIR)/rules.mk

endef

$(eval $(call BuildPackage,libsrtp))

这种相对前面的方式类似，只是这种软件包CMakelist.text要求需要创建build目录进行编译，因此在Makefile中添加CMAKE_BINARY_SUBDIR=build进行声明。因此在编译输出目录，可以看到openwrt会先创建build目录，而第一种方式是没有创建build目录。

软件包中只有部分CMakelist.text

这种方式就是软件包中没有提供完整的CMakelist.txt，但是提供了部分，需要用户包含提供部分的Cmakelist.txt实现，这种方式目前是通过打patches的方式生成主要CMakelist.txt。

Makefile文件

以上是通过打patches生成主CMakelist.txt，可以看到包含了mqttFilePaths.cmake文件。
