Source: https://github.com/harmony-55/harmonyos_samples/blob/main/frame-generation-vulkan-samplecode-clientdemo-cpp/entry/src/main/cpp/CMakeLists.txt

Lists all the source files for the sample application. Ensure all paths are correct relative to the CMakeLists.txt file.

```cmake
set(sample_src_files
    asset/AassetImporter.cpp
    vulkan_utils/Blit.cpp
    vulkan_utils/Camera.cpp
    vulkan_utils/MainSceneRenderer.cpp
    vulkan_utils/UIRenderer.cpp
    vulkan_utils/Utils.cpp
    vulkan_utils/DescriptorPool.cpp
    vulkan_utils/CommandPool.cpp
    vulkan_utils/Buffer.cpp
    vulkan_utils/Image.cpp
    vulkan_utils/Device.cpp
    common/timer.cpp
    common/log.cpp
    begin/core.cpp
    begin/hellovk.cpp
    napi_init.cpp
)
```

### Configure Not Trusting User-Installed CA Certificates

Source: https://github.com/harmony-55/harmonyos_samples/blob/main/BestPracticeSnippets/Privacy/privacy/src/main/ets/pages/Cybersecurity.md

Disable trust for CA certificates manually installed by enterprise MDM systems or device administrators, as well as those installed by the current user. This enhances security by limiting the trusted certificate authorities.

```json
{
  "network-security-config": {
    ...
  },
  "trust-global-user-ca": false,
  "trust-current-user-ca": false
}
```

Source: https://github.com/harmony-55/harmonyos_samples/blob/main/guide-snippets/MindSporeLiteKit/MindSporeLiteCDemo/README_zh.md

Instructions for cloning the project repository using Git, including sparse checkout configuration to download only the relevant demo directory.

```bash
git init
git config core.sparsecheckout true
echo MindSporeLiteKit/MindSporeLiteCDemo/ > .git/info/sparse-checkout
git remote add origin https://gitee.com/harmonyos_samples/guide-snippets.git
git pull origin master
```

### Download Project Files

Source: https://github.com/harmony-55/harmonyos_samples/blob/main/guide-snippets/CoreFile/UserFile/SelectingUserFiles/README_zh.md

Use these Git commands to clone the specific project directory for the user file selection sample.

```bash
git init
git config core.sparsecheckout true

### Install Git LFS Filter on Windows Command Prompt

Source: https://github.com/harmony-55/harmonyos_samples/blob/main/xengine-samplecode-vulkan-temporal-upscale-demo-cpp/entry/src/main/cpp/3rdParty/ktx/README.md

Installs the Git LFS smudge & clean filter for $Date$ keyword expansion on Windows using the Command Prompt. It requires git.exe to be in the system's PATH. It also forces a new checkout of affected files to apply the filter.

```cmd
install-gitconfig.bat
del TODO.md include/ktx.h tools/toktx/toktx.cpp
git checkout TODO.md include/ktx.h tools/toktx/toktx.cpp 
```

Use this command to start the development server, which compiles the project and enables hot-reloading for faster development cycles.

```bash
npm run serve
```
