Awesome! Thank you for the answers and the quick reply! I have only
been using CMake for a little over a year and again I am sorry for posting an incorrect answer. I always thought that I had to have one project() call for each add_executable and/or add_library. It is very good to know that that is not the case. However, I am curious if you think it is good practice to do such a thing?
To join this conversation late, but to give it a new twist with a new subject line it is typical practice to have one project() call (done in the top-level CMakeLists.txt file) for each software project (e.g., a complete source tree that is typically distributed as an independent tarball) no matter how many libraries and executables are built for that project. When I first learned CMake years ago I looked at a number of projects with CMake-based build systems to see what was typical usage, and I suggest you might want to do the same. I used to advocate studying the CMake-based build system for PLplot that I helped to implement, but that was essentially done so many years ago (although it is still maintained extensively) that I am sure there are much better best practices out there now especially considering all the additional useful CMake features that have been introduced over the years. I initially did a lot of my learning based on the CMake-based build systems for CMake itself and also for KDE so one of those might be worthy studying now, but they also might have the same problem (too many years of history without necessarily keeping up with best practices) that PLplot does. Are the CMake and KDE build systems still the best paradigms for study or are there better ones for study that can be recommended now? Alan __________________________ Alan W.
