Download this extension from the VS Gallery or get the CI build.
This extension adds options and menu entries for building, running and testing your Fortran project using the Fortran Package Manager (fpm).
In the Tools->Options dialog, find the entry "fpm Options", and specify the appropriate values for the various options.
Note that leaving an option blank is valid, as it means the extension will simply not include that in the options passed to fpm, and thus fpm will simply use the default.
Use one of the entries in the Extensions->fpm menu to execute fpm build, fpm run or fpm test, using the options specified in the previous step.
For background material and getting started, I found this video to be a great start, and of course the official documentation. Please open an issue to report a bug, or request a feature so that it can be discussed before submitting a pull request.
We would like to acknowledge the Nuclear Regulatory Commission (NRC) for providing the initial funding to develop this extension and for allowing us to make it open-source.
