How do I export compile_commands.json in CMake for C++?

To export the `compile_commands.json` file in CMake for C++, you can enable the generation of this file by adding a specific command in your `CMakeLists.txt`. This file is particularly useful for tools that need to understand the compilation process, like certain IDEs and static analysis tools. Here’s how to set it up:


        cmake_minimum_required(VERSION 3.5)
        project(MyProject)

        # Enable compile_commands.json generation
        set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

        add_executable(my_executable main.cpp)

The above lines enable the exporting of `compile_commands.json` for your C++ project.
