Updated Readme to match what is in CMakePresets.json

[jbyron1]

Was trying to build from source on linux and was having problems, realized that the instructions seem to have an additional parent directory above the build and install directories that the CMakePresets.json base preset does not have.

I modified the instructions for linux with the commands that worked for me, i assume the same changes would need to be made to the mac instructions, but i do not have a mac to test with.

Thanks for the PR!

I tested the README on my machine, and ideally the sequence should be:

sudo apt install mono-complete
# + install qt

git submodule update --init
cmake --preset=Debug

This will use the CMakePresets file + vcpkg

Overall the PR makes sense to me, but I'd prefer if we use the preset approach instead as it would align to what we do on CI as well, hence providing the end user the same build artifacts we product over here on Github.

I'll add a suggestion to the PR. But thanks for rising it up!

Preferring .build and .install as paths as they would be automatically ignored by our .gitignore
