# Since https://github.com/NixOS/nixpkgs/pull/60985, we add `/run-opengl-driver[-32]`
# to the `RUNPATH` of dispatcher libraries `dlopen()` ing OpenGL drivers.
# `RUNPATH` doesn't propagate throughout the whole application, but only
# from the module performing the `dlopen()`.
#
# Apitrace wraps programs by running them with `LD_PRELOAD` pointing to `.so`
# files in $out/lib/apitrace/wrappers.
#
# Theses wrappers effectively wrap the `dlopen()` calls from `libglvnd`
# and other dispatcher libraries, and run `dlopen()` by themselves.
#
# As `RUNPATH` doesn't propagate through the whole library, and they're now the
# library doing the real `dlopen()`, they also need to have
# `/run-opengl-driver[-32]` added to their `RUNPATH`.
#
# To stay simple, we add paths for 32 and 64 bits unconditionally.
# This doesn't have an impact on closure size, and if the 32 bit drivers
# are not available, that folder is ignored.
