[enchantum] fix cmake config path

[toge (toge)]

• 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, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Exactly one version is added in each modified versions file.

Problem

Upstream installs the CMake package files into two different locations:

• enchantumConfig.cmake / enchantumConfigVersion.cmake → <prefix>/cmake/
• enchantumTargets.cmake → <prefix>/share/enchantum/cmake/

The portfile called vcpkg_cmake_config_fixup(CONFIG_PATH "cmake"), which moves
only the config files into share/enchantum/, leaving the targets file behind in
share/enchantum/cmake/. Since enchantumConfig.cmake does
include("${CMAKE_CURRENT_LIST_DIR}/enchantumTargets.cmake"), any consumer using
find_package(enchantum CONFIG REQUIRED) fails with:

include could not find requested file:
  .../share/enchantum/enchantumTargets.cmake

Fix

Before running vcpkg_cmake_config_fixup, move the config files into
share/enchantum/cmake/ next to the targets file, then run the fixup with
CONFIG_PATH "share/${PORT}/cmake". The fixup then relocates all three files
together into share/enchantum/ and corrects the PACKAGE_PREFIX_DIR
computation.

GPT 5.6 Sol says:

The diagnosis in the PR description is correct, but the proposed relocation does not produce the claimed final layout.

At ports/enchantum/portfile.cmake lines 17-23, the two config files are first moved into share/enchantum/cmake/, then vcpkg_cmake_config_fixup(CONFIG_PATH "share/${PORT}/cmake") is called. A clean local install completed successfully, but installed:

share/enchantum/enchantumConfig.cmake
share/enchantum/enchantumConfigVersion.cmake
share/enchantum/cmake/enchantumTargets.cmake

The installed config still contains:

include("${CMAKE_CURRENT_LIST_DIR}/enchantumTargets.cmake")

Therefore both Release and Debug example configurations fail with:

include could not find requested file:
  .../share/enchantum/enchantumTargets.cmake

which is plausible; should we add a test port since the lab is clearly not exercising this?

Shock and horror the above review comment was wrong but I also asked it to add a test port, would you consider toge#34 ?

Thanks!

Why not a patch and proper upstreaming... at least opening an issue?

I thought it was specific to us due to where we required the CMake configs to go so I didn't ask to involve upstream.
