Without this the vscode extension cannot find the example executable, and the example fails.
Also use $USERPROFILE instead of $HOME for finding the `.vscode` user directory for installing the extension.
Bug: #12
`nlohmann/json` raises a `size_t` to `int` MSVC warning that will fail the build if `CPPDAP_WARNINGS_AS_ERRORS` is enabled.
Given that this is not our code, the best we can do is to make an exception for this warning.
