Excerpt: "The --trace option will print every line of CMake that is run. Since this is very verbose, CMake 3.7 added --trace-source="filename", which will print out every executed line of just the file you are interested in when it runs. If you select the name of the file you are interested in debugging (usually by selecting the parent directory when debugging a CMakeLists.txt, since all of those have the same name), you can just see the lines that run in that file. Very useful!"
