[Openmp-commits] [openmp] [OpenMP] Fix buildbot patch when openmp is enabled as project (PR #76141)

[Ethan Luis McDonough via Openmp-commits]

https://github.com/EthanLuisMcDonough created https://github.com/llvm/llvm-project/pull/76141

This patch addresses an issue introduced in pull request #74398. CMake will attempt to re-build gtest if openmp is enabled as a project (as opposed to being enabled as a runtime). This patch adds a check that prevents this from happening.
