* Use PROJECT_SOURCE_DIR rather than CMAKE_SOURCE_DIR to allow building as subdirectory
* Also use PROJECT_SOURCE_DIR instead of CMAKE_SOURCE_DIR in c/cxx api examples
* Only build examples by default when not building as subdirectory
* Do not suggest building binaries either

* Support using onnxruntime 1.16.0 with CUDA 11.4 on Jetson Orin NX.
The pre-built onnxruntime libs are provided by the community
using the following command:
```bash
./build.sh --build_shared_lib --config Release --update \
--build --parallel --use_cuda \
--cuda_home /usr/local/cuda \
--cudnn_home /usr/lib/aarch64-linux-gnu 2>&1 | tee my-log.txt
```
