[Bug] Intel oneAPI 2025.2 flag change

[scivision]

Describe the issue

Intel oneAPI 2025.2 introduces a new flag that emits warnings when building any project with googletest. This fails builds that have CMAKE_COMPILE_WARNING_AS_ERROR=1.

This is an environment regression, so we will provide a trivial patch for oneAPI 2025.2 or newer in #4798

Steps to reproduce the problem

git clone https://github.com/scivision/googletest-oneapi-demo

git switch main

cmake -Bbuild -DCMAKE_COMPILE_WARNING_AS_ERROR=1

cmake --build build

That will error with Intel oneAPI 2025.2 on Linux.

To use our patched googletest, do the following

# from googletest-oneapi-demo/ directory

git switch patch-oneapi

cmake -Bbuild -DCMAKE_COMPILE_WARNING_AS_ERROR=1

cmake --build build

That build will success on Intel oneAPI 2025.2 and previous oneAPI versions.
