That is currently OK, since we always set LD_LIBRARY_PATH to a non-empty value. However, we're soon to stop setting it at all. So, if the user has an empty (or no) LD_LIBRARY_PATH in his envirnment, we'd end up adding the current working directory to LD_LIBRARY_PATH (as an empty entry in a colon-separated list is most probably interpreted as meaning the current working directory, which we do know can cause issue, and which we expressely check against in support/dependencies/dependencies.sh Fix that by only using an existing LD_LIBRARY_PATH if it is not empty. Also use a Makefile construct as it is easier to read than a shell one (we can do that, as all variables from the environment are available as make variables). Signed-off-by: "Yann E.
