But I was looking for a way to add these directories to the runtime library search path of the executable. I think, it's more convenient, if an executable finds its libraries without any special runtime configuration as long as these libraries are in the same directory as at compile time.

OK. To learn about that you need to read up on rpath. CMake's wiki article https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling <https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling> is a good place to start.
