Is this needed given that we already include sys/ptrace.h from debugger.h. And if it's needed for cross-compiling, will it cause issues when building for Android using the Android NDK?

"Cross-compiling for aarch64 Linux"?

```
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../Linux/arm64.toochain.cmake ..
cmake --build . --config Release
```

Note #1: 64-bit build will also run against 32-bit targets on Windows and Linux operating systems

Note #2: Encountering problems creating a 32-bit build on 64-bit Windows due to the environment not being properly set up and libraries missing? Open the generated .sln file in Visual Studio and build from there instead of running cmake --build. Also note that 64-bit build is going to work on 32-bit targets, so creating a 32-bit build might not be necessary.
