Test that binaries that use external libraries work When we link to an external library either with find_library() without any dirs:, or with dependency(), we should be able to run uninstalled out of the box without having to set any environment variables or other shenanigans. This is especially important on macOS because only the system frameworks directory is in the default runtime path, and all other frameworks and libraries need to be found with RPATH or absolute path to the dylib.

macos: Rewrite install_name for dependent built libraries on install On macOS, we set the install_name for built libraries to @rpath/libfoo.dylib, and when linking to the library, we set the RPATH to its path in the build directory. This allows all built binaries to be run as-is from the build directory (uninstalled). However, on install, we have to strip all the RPATHs because they point to the build directory, and we change the install_name of all built libraries to the absolute path to the library. This causes the install name in binaries to be out of date. We now change that install name to point to the absolute path to each built library after installation. Fixes https://github.com/mesonbuild/meson/issues/3038 Fixes https://github.com/mesonbuild/meson/issues/3077 With this, the default workflow on macOS matches what everyone seems to do, including Autotools and CMake. The next step is providing a way for build files to override the install_name that is used after installation for use with, f.ex., private libraries when combined with the install_rpath: kwarg on targets.
