# Represents a CI build configuration flavor

# This primarily consists of the operating system, but can contain a hierarchical set
# of parameters as well.
# A platform flavor is represented as a /-separated string, with the first element
# typically being the operating system, e.g. "Linux/Qt6" or "Windows/Qt5/static".
#
# Platform flavors are matched hierarchically against (partial) platform flavors
# in CI configuration files, ie. a configuration for "Linux" applies to "Linux/Qt5".
