After some research and experimental research, I solved my problem. However, here is what I learned in this process.
The first attempt is to add the file to the root directory of the project and mark it as a resource. After the publication, it worked. But the presence of these files in the project is its root lame.
Since I need some * .exe files compiled in another VS solution, they were added as a reference to the project. I tried it and it passed the Publish test. But still ... not the best way to do this.
After that, with some scenarios and an event after the build, I copied the necessary files to the right folder. It works .. but after publication they do not appear in the package.
However, with the tool of the Magician, there is still the possibility:

This led to some promising experiments, but they helped me understand how limited MS ClickOnce is, so I decided to try other tools.
Here's a good start: What alternatives are available for ClickOnce?
