I'm a bit concerned about this name. When I put "dmon" into repology I get an existing hit (https://repology.org/project/dmon/versions) for https://github.com/aperezdc/dmon rather than this library, but googling for "dmon c++" returns this one. Would you be willing to accept septag-dmon?

[BillyONeal]

Looks great as long as we are OK with the name.

[BillyONeal]

(I asked other maintainers what they think on the name BTW, but if you'd accept the longer name it would short circuit that)

[vicroms]

To avoid confusion for users and in the spirit of fairness. We should name this port septag-dmon and disallow any port to be named just dmon in the future.

If the project Billy mentioned gets added to vcpkg it will have to be named aperezdc-dmon.

This also prevents issues with versioning where old versions of the port would be named differently and have their own versions file and database entries.

Thanks for the new port!
