# Support macros for creating Calamares branding components.
 | 
						|
#
 | 
						|
# Calamares branding components have two parts:
 | 
						|
# - a branding.desc file that tells Calamares how to describe the product
 | 
						|
#   (e.g. strings like "Generic GNU/Linux") and the name of a QML file
 | 
						|
#   (the "slideshow") that is displayed during installation.
 | 
						|
# - the QML files themselves, plus supporting images etc.
 | 
						|
#
 | 
						|
# Branding components can be created inside the Calamares source tree
 | 
						|
# (there is one example the `default/` branding, which is also connected
 | 
						|
# to the default configuration shipped with Calamares), but they can be
 | 
						|
# built outside of, and largely independently of, Calamares by using
 | 
						|
# these CMake macros.
 | 
						|
#
 | 
						|
# See the calamares-examples repository for more examples.
