In order to use the mxnet cpu binary available at https://mxnet.incubator.apache.org/install/index.html?platform=MacOS&language=R&processor=CPU I needed to compile opencv with `opencv_hdf` and `opencv_text` support (which is not the default for the homebrew bottle currently).
```diff
diff --git a/Formula/opencv.rb b/Formula/opencv.rb
index 1ac968d75e..1a7f05c92a 100644
--- a/Formula/opencv.rb
+++ b/Formula/opencv.rb

```
Then it can be installed with the following and the library can be loaded.
```shell
brew install opencv --build-from-source
```
