In Fedora rebuilds to test package build reproducibility (see https://reproducible-builds.org/, https://fedoraproject.org/wiki/Changes/ReproduciblePackageBuilds), we get the following differences like the following for various CMakeLists.txt and SConstruct files: /usr/share/cantera/samples/cxx/LiC6_electrode/CMakeLists.txt: │ │ -include_directories("/usr/include" "/usr/include/eigen3" "/usr/include/highfive") │ │ +include_directories("/usr/include/highfive" "/usr/include/eigen3" "/usr/include") Those end up in the -debugsources package and cause the whole build to be flagged as irreproducible. In addition, if the an include file with the same name happened to be present in more than one location, the unpredictable sort order would mean that different files would be used in different builds. Sort the directories alphabetically for predictable results.
The message would vary between reruns, which is not useful.
