We do it right in [compiler-rt/CMakeLists.txt](https://github.com/llvm/llvm-project/blob/main/compiler-rt/CMakeLists.txt):
```cmake
# We support running instrumented tests when we're not cross-compiling
# and target a UNIX-like system or Windows.
# We can run tests on Android even when we are cross-compiling.
