This didn't trip me up for too long since I'm used to problems with C++ version dependencies, but I suffered a small setback because I used std::popcount, which is only in C++20, in my exercise3 solution. I was getting an error popcount is not a member of std, which I fixed by taking a quick peek at the previous labs' code and adding the following line to my dv CML: target_compile_features(tests PRIVATE cxx_std_20)
It might be nice to include a quick comment that this line is necessary to use C++20 language features.
