Hello again,
I ended up solving the issue by following the steps in the following tutorial (for future reference):
https://docs.microsoft.com/en-us/cpp/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp?view=vs-2019
Essentially, I was missing one step : copying the provided .dll next to the executable .exe in my build folder (as recommended in the tutorial). I come from a linux background … I still have to work on my windows devops skills I guess.
Thanks for the quick response!
Cheers
