Unable to use run-vcpkg properly

[Milerius]

Hello i got the following error:

##[error]run-vcpkg action execution failed: Error: Unable to locate executable file: git. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable

sorry was a mistake of syntax using env github variable

[lukka]

@Milerius thanks for the report! It looks like the problem was referencing environment variables in the env property of an action, e.g. PATH: $PATH:${{ github.workspace }}/new/path would not expand $PATH, while PATH: ${{ env.PATH }}:${{ github.workspace }}/new/path would expand PATH as well.

In my experience I have seen other source of problems:

• using the colon as path separator, which depends on the shell used in the step;
• using ${{ github.workspace }} in an action on Windows that uses the bash shell, since the paths in the github context are in Windows form, i.e. c:\path\;

To be platform agnostic, it usually it works best to use the bash shell on any OS, and using add-path to augment the path.
