Can you elaborate on the consequences and reason for this change?

[jiayuehua]

If installed to include/foonathan, then client code must use
include "foonathan/foonathan/memory…" other than include "foonathan/memory".

after this fix, some other vcpkg port that already rely on your memory lib can work again.

also from microsoft/vcpkg#30212

CMake Error in src/cpp/CMakeLists.txt:
  Imported target "foonathan_memory" includes non-existent path

    "D:/installed/x86-windows/include/foonathan_memory"

  in its INTERFACE_INCLUDE_DIRECTORIES.

Okay, that's fair. Thanks.
