# CMAKE_EXPORT_COMPILE_COMMANDS

Enable/Disable output of compile commands during generation.

If enabled, generates a `compile_commands.json` file containing the exact compiler calls for all translation units of the project in machine-readable form. The format of the JSON file looks like:

    [
      {
        "directory": "/home/user/development/project",
        "command": "/usr/bin/c++ ... -c ../foo/foo.cc",
        "file": "../foo/foo.cc"
      },

      ...

      {
        "directory": "/home/user/development/project",
        "command": "/usr/bin/c++ ... -c ../foo/bar.cc",
        "file": "../foo/bar.cc"
      }
    ]

Note

This option is implemented only by Makefile Generators and the `Ninja`. It is ignored on other generators.
