Thanks.  I opened an issue for it:

  https://gitlab.kitware.com/cmake/cmake/issues/18202

Please see that issue for further discussion.

If no project() command appears anywhere in the top-level CMakeLists.txt
file then one is injected on line zero.  That is the one that causes
the warning.  When it is present in the inline macro then no injection
is done.  It's strange but that's how things evolved.
