LNK2005 crc32 已经在 crc32.obj 中定义 and warning C4267: “参数” : 从“size_t”转换到“const int”，可能丢失数据

### Checklist

- [X] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues).
- [X] For Python issues, I have tested with the [latest development wheel](http://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [X] I have checked the [release documentation](http://www.open3d.org/docs/release/) and the [latest documentation](http://www.open3d.org/docs/latest/) (for `master` branch).

### Steps to reproduce the issue

#### I first cloned Open3D by:
```
git clone --recursive https://github.com/isl-org/Open3D
cd Open3d
git tag
git checkout v0.15.1
git submodule update --init --recursive
```

#### Then, I build Open3D (on Ubuntu 20.04, with CUDA 11.5) with:
```
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_INSTALL_PREFIX="E:/dev_install/o3d_install" ..
cmake --build . --config Release --target ALL_BUILD
```

### Error message

```shell
See error
```

### Open3D, Python and System information

```markdown
- Operating system: Windows 10 64-bit
- Python version: Python 3.8
- Open3D version: v0.15.1
- System architecture: x86
- Is this a remote workstation?: no
- How did you install Open3D?: build from source
- Compiler version (if built from source): Visual Studio 2019
```
