From this blog post, it appears that the usage of JeroMQ (a pure-java implementation of ZeroMQ) is the easiest route to go.
1. Clone the repo from https://github.com/zeromq/jeromq
2. Install maven
3. get into the repository root and build with
mvn package
4. Put the .jar file [somewhere]
5. Add [somewhere] to your javaclasspath
6. Import the package and enjoy!
Edit
Adding the following useful links with example matlab code

From this post we can understand that the latest Matlab versions do not work with the latest JDK versions. Only 7 or 8 are supported.
But last version of JeroMQ from gihub seems to use JDK with version >=9. Because after I ran the example from git I got exception like this:
java.lang.NoSuchMethodError: java.nio.ByteBuffer.clear()Ljava/nio/ByteBuffer;
at zmq.Signaler.send(Signaler.java:134)
...
I wonder if anyone has solved the JeroMQ in Matlab problem. Seems impossible.

It is not impossible. You need to change your default JDK to 1.8 and compile it again with the command below.
mvn clean package
I tested this on Matlab R2022a and it works fine. If that doesn't work somehow, just change the compiler properties inside the pom.xml from 8 to 1.8(It's the same thing but give it a try). Lastly, add this to properties
<maven.compiler.release>8</maven.compiler.release>
or
<maven.compiler.release>1.8</maven.compiler.release>
