Enabling and Disabling Compilation Macros

The following is the configuration method for controlling the activation status of compilation macros (using the WITH_PTCS_USE macro as an example).

Ubuntu System Configuration

Method 1：Command Line Configuration

1. Enter the build directory：

   cd build

2. Run the CMake command：

   cmake .. -DWITH_PTCS_USE=true  # Enable macro

   or

   cmake .. -DWITH_PTCS_USE=false  # Disable macro

3. Error Handling： If the configuration fails, please clear the build directory and try again:

   rm -rf ./*  # Warning: This operation will permanently delete all files in the build directory

   Then re-run the CMake command.

Method 2：CMake GUI Tool

1. Install the tool：

   sudo apt install cmake-gui

2. Run the tool：

   cmake-gui

3. Set project paths：
   • Source path: Select the HesaiLidar_SDK_2.0 directory
   • Build path: Select the HesaiLidar_SDK_2.0/build directory
4. Configure macro status： Find the WITH_PTCS_USEoption in the interface and set its value to enable or disable (usually located under the WITH section):
   • ✅ Checked: Enable macro
   • ⬜ Unchecked: Disable macro
5. Manually add the macro (optional)： If this option is not found, click Add Entry to add it:
   • Key：WITH_PTCS_USE
   • Type：BOOL
6. Generate project： Click the Configure → Generate buttons in sequence to generate the configuration project.

Windows System Configuration

1. In the parameter list, find the WITH_PTCS_USE option：
   • ✅ Checked: Enable macro
   • ⬜ Unchecked: Disable macro
2. Manually add the macro (optional)： If this option is not found, you can add it under Add Entry:
