# 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
