zeromq version incompatible

[Thomas-AnhDao]

I set up a LTC testnet blockbook API, but after finish sync, it is automatically closed. The error message like below:

E0405 01:06:23.617231    4649 bitcoinrpc.go:169] mq: zmq4 was installed with ZeroMQ version 4.3.5, but the application links with version 4.3.2
E0405 01:06:23.617387    4649 blockbook.go:305] initializeMempool zmq4 was installed with ZeroMQ version 4.3.5, but the application links with version 4.3.2
I0405 01:06:23.617570    4649 rocksdb.go:173] rocksdb: close

From the beginning, I installed the newest version of ZeroMQ from its github (4.3.5). After got the error above, I downgrade it:

pkg-config --modversion libzmq
4.3.2

But still got this error. Blockbook version: 0.4.0

@Thomas-AnhDao How did you resolve this error?

@Mack-Mohan actually I turned to use blockbook service from Getblock, I didn't use the self-build
