[Scons-users] 回复：回复：回复：回复：回复：回复： Ninja compilation fails after using include path file instead of "-I" option

Okay that indicates that scons is not deciding to build and execute the
ninja file, probably because nothing has changed in the build scripts when
you only change the source file. This is a bug, even if the ninja file is
not regened, scons should execute it for you. I will make a PR for this
issue. For now you will need to use the  run_ninja_env.bat.
