I just discovered that many Linux distros these days use the --as-needed Linux linker option by default. At first glance that option makes a lot of sense since it tends to reduce startup times. But I guess there are some caveats as well which is probably why CMake does not adopt this linker option by default for Linux builds. However, I would at least like to try this option for my own Linux builds without forcing it using target_link_libraries. Is it possible to specify linker options such as --as-needed using environment variables and/or -D options?
