CMAKE_EXPORT_COMPILE_COMMANDSΒΆ
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.
This option currently does not work well in combination with
the UNITY_BUILD target property or the
CMAKE_UNITY_BUILD variable.
