# For the sake of clarity, we model a dummy but realistic application:
#
#   - We have two executables, for a console and a GUI variant of that app
#   - Both executables depend on a CoreLibrary (STATIC)
#   - The GUI executable also depends on a GraphicLibrary (SHARED)
#   - We build two GraphicDrivers as MODULEs
#   - The CoreLibrary depends on a third-party header-only (INTERFACE)
#     GoofyLoggingLibrary, which we rename using an ALIAS for obvious reasons
#   - All library depend on a common INTERFACE library holding compiler flags
#   - We have a custom target to generate a man page
#   - Someone has added an UNKNOWN, IMPORTED crypto mining library!
#   - We have a circular dependency between two libraries
