Quoting for the EXAMPLES.md file :

Second, determine a suitable package name. This should be ASCII, lowercase, and recognizable to someone who knows the library's "human name". If the library is already packaged in another package manager, prefer that name.

Eigen is known as:

  • Eigen3 as CMake package (see FindEigen3.cmake and Eigen3Config.cmake distributed by the project).
  • libeigen3-dev in Debian-based systems.
  • eigen3 in FreeBSD [1]
  • eigen3 in MacPorts [2]
  • eigen in homebrew [3]
  • eigen3 in fedora [4]
  • eigen in Gentoo [5]
  • eigen3 in MINGW [6]

Given that (except for homebrew and gentoo's portage) the Eigen package is always called eigen3, it could make sense to call it eigen3 also in vcpkg?

Yes, this should definitely be renamed to eigen3! Great detective work.
