• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

https://github.com/karastojko/mailio/blob/8a3b92361d244dbb1af722d1ad6dcaf321907936/CMakeLists.txt#L62
find_package(Boost REQUIRED COMPONENTS system date_time regex unit_test_framework)

, I just have add patch and remove boost-test denendency.

The usage test passed on x64-windows (header files found):

mailio provides CMake targets:

  # this is heuristically generated, and may not be correct
  find_package(mailio CONFIG REQUIRED)
  target_link_libraries(main PRIVATE mailio)
