Instructions to run the project can be found in the readme, but I will include it here aswell:

Instructions

The imageName has to be chosen! ("cmakeFight" could be a fitting name)

1. Build the image via (getting all dependencies will take some time)

docker buildx build -t <imageName> .

2. Run the container

docker run -it --mount type=bind,src=.,dst=/mnt/host/cmake-exercise <imageName>

3. Change directory into the repo

cd cmake-exercise

4. Run the shell script (build folder should not exist beforehand!)

./build_and_run.sh

Expected output:

Let's fight with CMake, Docker, and some dependencies!
