# Make an explicit list of all source files in IFJ23_INC. This is important
# because CMake is not a build system: it is a build system generator. Suppose
# you add a file foo.cpp to src/ after running cmake .. . If you set
# IFJ23_INC with `file(GLOB ... )`, this is not passed to the makefile; it
# doesn't know that foo.cpp exists and will not re-run cmake. Your
# collaborator's builds will fail and it will be unclear why. Whether you use
# file(GLOB ...) or not, you will need to re-run cmake, but with an explicit
# file list, you know beforehand why your code isn't compiling.

# Form the full path to the source files...
