 This will output a binary `euphoniumcli` which can be later executed to run the platform. The web-ui will be available on port `80` by default.
 If you have trouble using port 80 (on Linux for example), use `cmake .. -D HTTP_SERVER_PORT=8080` to change the web-ui port.
 
+#### Hint for Linux Mint
+In order for the CLI build to work on Linux Mint I had to add a little extra CLI arg to the `cmake` command, as it doesn't know how to find the correct library it would seem.
+Maybe this could be added directly into the `cmake` setup?
+
+To fully compile the `cli` on Linux Mint execute the following
+```
+cmake -DCMAKE_CXX_STANDARD_LIBRARIES="-lX11 -ldl" ..
+make
+```
