This argument allows to specify the path to make which is used by
LLDB API tests to compile test programs.
It might come in handy for setting up cross-platform remote runs of API tests on Windows host.
It can be used to override the make path of LLDB API tests using `LLDB_TEST_USER_ARGS` argument:
```
cmake ...
-DLLDB_TEST_USER_ARGS="...;--make;C:\\Path\\to\\make.exe;..."
...
```
