Comment (by yan12125):

 As far as I understand it, this is a Wireshark-specific issue rather than
 a generic cmake one. Wireshark
 [https://github.com/wireshark/wireshark/blob/fe76be0b5bcbb465d4b510135922ea3302c8c705/CMakeLists.txt#L968-L970
 detects lz4 in its CMakeLists.txt], and it can be disabled with
 `-DENABLE_LZ4=OFF`.

 lz4 is used in "Apache Cassandra CQL dissection" and "Kafka Protocol
 dissection". I'm not sure if those protocols are common or not.
 Considering that lz4 is a rather tiny package (112K tbz2 for Darwin 17),
 it won't hurt anyone to put it into depends_lib of wireshark2.
