unset `LLVM_RUNTIMES_BUILD` after this again?, since it is not a runtimes build. Coud be done most elegantly by warpping this code into a function, so LLVM_RUNTIMES_BUILD is only set in its scope.

Also consider adding a comment in the sense of:
```cmake
# LLVM_RUNTIMES_BUILD avoids gtest to link to LLVMSupport, which might be incompable with the platform libomp is compiled for.
set(LLVM_RUNTIMES_BUILD 1)
```
