Add manifold port

[JeffreyWardman]

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

I was able to build locally. manifold builds files into lib/cmake which raises warnings, which seem to have caused the CI/CD to fail. Once adding the ignore warnings, I get the current errors only in CI/CD.

Initial error due to warnings: https://dev.azure.com/vcpkg/public/_build/results?buildId=109648&view=logs&j=878666d5-db33-5b27-9e7d-b0c7ee352005&t=69176ca8-c93b-5311-0f74-6cb12a2b3f92&l=8209

After adding the ignore fixes: https://dev.azure.com/vcpkg/public/_build/results?buildId=109649&view=logs&j=878666d5-db33-5b27-9e7d-b0c7ee352005&t=69176ca8-c93b-5311-0f74-6cb12a2b3f92&l=8184

This is my first commit to vcpkg. It'd be great if I can get advice on how to handle these kinds of warnings for it to be merged.

This is my first commit to vcpkg. It'd be great if I can get advice on how to handle these kinds of warnings for it to be merged.

Usually these kinds of problems require patching upstream's build system, or moving around bits in portfile.cmake.

Do you have specific questions about the warnings? They seem pretty explicit in what the problem is to me, but then again, I wrote most of the messages 😅

Repeating the errors here so that the logs aren't lost when the build gets purged in a few days:

D:\a_work\1\s\ports\manifold\portfile.cmake: warning: ${CURRENT_PACKAGES_DIR}/debug/include should not exist. To suppress this message, add set(VCPKG_POLICY_ALLOW_DEBUG_INCLUDE enabled)
note: If this directory was created by a build system that does not allow installing headers in debug to be disabled, delete the duplicate directory with file(REMOVE_RECURSE "${CURRENT_PACKAGES_DIR}/debug/include")
D:\a_work\1\s\ports\manifold\portfile.cmake: warning: This port installs the following CMake files in places CMake files are not expected. CMake files should be installed in ${CURRENT_PACKAGES_DIR}/share/${PORT}. To suppress this message, add set(VCPKG_POLICY_SKIP_MISPLACED_CMAKE_FILES_CHECK enabled)

D:\a_work\1\s\ports\manifold\portfile.cmake: warning: Found 3 post-build check problem(s). These are usually caused by bugs in portfile.cmake or the upstream build system. Please correct these before submitting this port to the curated registry.
error: building manifold:x86-windows failed with: POST_BUILD_CHECKS_FAILED

[BillyONeal]

We can't merge ports which fail these kinds of post-build checks into the curated registry. You will need to fix these problems in the build system.

[JeffreyWardman]

The warnings are very clear to me! I'll fix the issues in the next day or two

This should resolve the issue with lib/cmake. Please use the actual path.

Formatting as printed by the heuristics:

Suggested change

	The package manifold provides CMake targets:
	find_package(manifold CONFIG REQUIRED)
	target_link_libraries(main PRIVATE manifold::manifold)
	manifold provides CMake targets:
	find_package(manifold CONFIG REQUIRED)
	target_link_libraries(main PRIVATE manifold::manifold)

If the heuristics has the same output, a usage file is redundant.
