5 RT_Thread Studio到底是用什么工具构建的？Scons还是Cmake？为什么我把SConstruct删掉，还是正常构建？

因为我在RT_Thread Studio上新建5.1.0版本工程时遇到了warning，最后找到是没有定义__RT_KERNEL_SOURCE__这个宏定义导致的。

然后找到了这个issues：https://github.com/RT-Thread/rt-thread/issues/9536
可是我把cmake.py内容复制过来之后，还是同样的问题，没有任何改变，于是我在src文件夹的sconscript文件加入了print打印语句，但看不到任何打印，继而又试了env.Print()什么的，一样看不到打印内容。
于是我直接把sconscript文件删掉，又把SConstruct删掉，最后重新构建，还是一样没有任何区别（修改过多处源文件结果都一样）
最后我不禁怀疑，其实studio使用的就是cmake。
是这样吗？
