Tao Xu 514285890c Enable QNNPACK for iOS (#24030)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/24030

The cmake arg - `USE_QNNPACK` was disabled for iOS build due to its lack of support for building multiple archs(armv7;armv7s;arm64) simultaneously.To enable it, we need to specify the value of IOS_ARCH explicitly in the build command:

```
./scripts/build_ios.sh \
-DIOS_ARCH=arm64 \
-DBUILD_CAFFE2_MOBILE=OFF \
```
However,the iOS.cmake will overwirte this value according to the value of `IOS_PLATFORM`. This PR is a fix to this problem.

Test Plan:
- `USE_QNNPACK` should be turned on by cmake.
- `libqnnpack.a` can be generated successfully.
- `libortch.a` can be compiled and run successfully on iOS devices.

This directory contains the useful tools.

build_android.sh

This script is to build PyTorch/Caffe2 library for Android. Take the following steps to start the build:

  • set ANDROID_NDK to the location of ndk
export ANDROID_NDK=YOUR_NDK_PATH
  • run build_android.sh
#in your PyTorch root directory
bash scripts/build_android.sh

If succeeded, the libraries and headers would be generated to build_android/install directory. You can then copy these files from build_android/install to your Android project for further usage.

You can also override the cmake flags via command line, e.g., following command will also compile the executable binary files:

bash scripts/build_android.sh -DBUILD_BINARY=ON

build_ios.sh

This script is to build PyTorch/Caffe2 library for iOS, and can only be performed on macOS. Take the following steps to start the build:

  • Install Xcode from App Store, and configure "Command Line Tools" properly on Xcode.
  • Install the dependencies:
brew install cmake automake libtool
  • run build_ios.sh
#in your PyTorch root directory
bash scripts/build_ios.sh

If succeeded, the libraries and headers would be generated to build_ios/install directory. You can then copy these files to your Xcode project for further usage.
