C++ challenge.

When I try to run the `your_program.sh` on my Mac to test my code, I get the error

```auto
CMake Error at /opt/homebrew/share/cmake/Modules/CMakeDetermineSystem.cmake:152 (message):
  Could not find toolchain file: /scripts/buildsystems/vcpkg.cmake
Call Stack (most recent call first):
  CMakeLists.txt:3 (project)

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

```

Any help would be greatly appreciated!

Hey @mikkel-larsen you’ll need to install [vcpkg](https://vcpkg.io/en/), and set the `VCPKG_ROOT` environment variable to the path where vcpkg is installed.
