MarsSeed [1] filed a deletion request for mongoose-server [2]: This minimal wrapper around the http server named mongoose has last been released in 2016. [a] Supposedly it was for mongoose 6. Current mongoose is at v7.11. It is doubtful that this old wrapper would work with that. Also upstream project name is misleading, can be considered hostile: mongoose is a (http) server, so naming an unrelated project mongoose- server is problematic at the least. Packaging is also wrong: this wrapper embeds mongoose in a way that instructs cmake to download mongoose from its repo during build. Anyway, it's best to delete this deprecated package.
