Colleagues, please tell me how to solve my problem - I want the program have set setuid after compilation.

Right now I’m using a very simple CMakeLists.txt:

```auto
set (HEADERS ...)
set (SOURCES ...)

add_executable myprog ${HEADERS} ${SOURCES})
target_link_libraries(...)

```

Thanks in advance for the advice,  
Ogogon.

I think it must be down at the installation step.  
See the parameter PERMISSIONS of the `install()` command.

Thank you. I found this in the documentation and did it. Entered **PERMISSIONS SETUID**.  
But this only works when I say **make install**.

Is it possible to make setuid installed after **make**?

I don’t think so, but I am still learning CMake, so maybe it is possible…

The question is rather if this is a good thing to do. As a normal user, you cannot set an executable as suid-root, only root user can do this. This might need a password during build and this will fail in a non-interactive shell or the prompt drowns in the output.
