# c-ares searching for gethostbyname in the libnsl library, however in the
# version that shipped with gRPC it doing it wrong [1], since it uses
# CHECK_LIBRARY_EXISTS(), which will return TRUE even if the function exists in
# another dependent library. The upstream already contains correct macro [2],
# but it is not included in gRPC (even upstream gRPC, not the one that is
# shipped with clickhousee).

# [1]: https://github.com/c-ares/c-ares/blob/e982924acee7f7313b4baa4ee5ec000c5e373c30/CMakeLists.txt#L125

#
# And because if you by some reason have libnsl [3] installed, clickhouse will
# reject to start w/o it. While this is completelly different library.
