Qt5 directory on macOS Big Sur (M1)

[erickisos]

Hi!

First of all, this is not a problem with PlotJuggler.

Problem description

I recently cloned the repo and when I was trying to compile it, I get an error message saying that Cmake can't find Qt5.
I solved this using Qt5_DIR flag pointing to homebrew dir (/opt/homebrew/qt@5/), anyway, I read in the CMakeLists.txt  that in fact, exist a flow control for APPLE which check for /usr/local/opt/qt5 so I can write the change to make it work by default on my M1, but I need to confirm, does anyone else with macOS confirm that the default installation on homebrew is that dir? I need some confirmation about that before making any changes to the CMake file.

Steps to reproduce (important)

• macOS Big Sur (Apple M1)
• You can reproduce this using the default cmake on the same platform.

I think this would be environment specific since I can build on bigsur but was getting zmq.h errors until I simply copied it manually and rebuilt. I installed qt via the qt installer gui and everything else via brew. It crashes a lot though on Mac. Tried main (master), 3.2 release, etc so it’s likely just that this is less tested on mac.

As for your specific question, I added the brew directories to my path (via the zshrc) to get it to compile but that’s needed for most thing brew related.

For the zmq.h error, I did the following to make it work :
cmake .. -DCMAKE_CXX_FLAGS="-I$(brew --prefix zmq)/include"

On macOS Monterey the following path is used /opt/homebrew/opt/zeromq
