# TODO: this is a bit of a hack to cross compile to Apple Silicon. libcxx
# starting with 11 enables CMAKE_BUILD_WITH_INSTALL_NAME_DIR which requires
# platform setup for rpaths. In cmake, this is enabled when macos is newer
# than 10.5. However CMAKE_SYSTEM_VERSION is set to empty (TODO: why?)
# which prevents the conditional configuration, and configure fails. The
# value here corresponds to `uname -r`. If stdenv.hostPlatform.release is
# not null, then this property will be set via mkDerivation (TODO: how can
# we set this?).
