Problem with header file dependency

Accelerated Computing CUDA CUDA NVCC Compiler
#1

Hi have problem with the dependency of header file using nvcc compiler,
it seams that dependency of the header file are not handled correctly by nvcc so when a header file is modified the
source code using it is not recompiled.
I’ve experienced this problem both with ninja and make build.

Is there a compilation flag I need to enable to avoid this problem?

in the attache zip a simple project with make where I verified the above problem.

It would be helpful if someone can answer this question.

Do we need to remove objects every time we rebuild a SW using nvcc because of improper header dependencies handling?
Thanks
