### Additional context

_No response_

Reproduce the failure with `./vcpkg install openjph:x86-windows-static`, then inspect `ports/openjph/portfile.cmake` and the referenced `install-x86-windows-static-dbg-out.log` and `-err.log` files. The fix is complete when the OpenJPH port builds and installs successfully for the Windows static triplet.
