CMAKE_EXPORT_COMPILE_COMMANDSΒΆ
New in version 3.5.
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"
}
]
This is initialized by the CMAKE_EXPORT_COMPILE_COMMANDS environment
variable.
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.
