Describe the bug

Here I have attached the failure logs from the vcpkg CI

If you notice, it doesn't find the includes for filesystem:

-- Looking for C++ include filesystem
-- Looking for C++ include filesystem - not found
-- Looking for C++ include experimental/filesystem
-- Looking for C++ include experimental/filesystem - not found

failure logs for x64-osx.zip

Steps to Reproduce
