Thanks.
I am not necessarily looking for a tutorial example but code that does it correctly, period.
In learning CMake I am coming to understand that finding things is an important part and qt/qtbase seems to have a lot of that.
Did not know that Qt had its own make tool, but then never programmed in Qt. Will take into consideration when looking at their code.
On a side note, learned a lot from
Deep CMake for Library Authors - Craig Scott - CppCon 2019
and like the Recommended Practices in your book, “Professional CMake A Practical Guide” ![]()
