examples : remove references to `make` in examples [no ci] (#15457)

This commit removes references to `make` in the examples, as the build
system has been updated to use CMake directly and using `make` will now
generate an error since Commit 37f10f955f70e0158d50343d0b9a3f92d194daae
("make : remove make in favor of CMake (#15449)").
