Thank you.

Hello @joemsong do you mind to download the latest version of catch2 (catch.hpp) - https://github.com/catchorg/Catch2/releases and replace with the catch.hpp file in ensmallen/tests/ (https://github.com/mlpack/ensmallen/blob/master/tests/catch.hpp) and see if that works?

Instructions:

git clone https://github.com/mlpack/ensmallen.git
cd ensmallen/tests
rm catch2.hpp
wget https://github.com/catchorg/Catch2/releases/download/v2.13.4/catch.hpp
cd ..
mkdir build
cd build
cmake ..
make

You might have to install armadillo before that:

brew install armadillo

@joemsong it's a bug in Catch2; see catchorg/Catch2@a25c1a2
