Another example where my_lib is a shared library

[nejcgalof]

It is possible to create another example like my_lib where my_lib is a shared library (.so). I try it, but I have problems when I link it to the tests. It is good practice to test a shared library in this way, or is it better to create a static and shared library, and link a static to the tests?

Specially I have the problem with target_link_libraries(demo_shared PRIVATE project_options project_warnings).
Then got the error:

Because of this, an example of a shared library will be good.

We should be able to do that by setting BUILD_SHARED_LIBS for my_lib.
