|

# When packaging Dolphin for an OS distribution, distro vendors usually prefer
|
||||
# to limit vendored ("Externals") dependencies as much as possible, in favor of
|
||||
# using system provided libraries. This modules provides an option to allow
|
||||
# only specific vendored dependencies and error-out at configuration time for
|
||||
# non-approved ones.
|
||||
#
|
||||
# Usage:
|
||||
# $ cmake -D APPROVED_VENDORED_DEPENDENCIES="a;b;c;..."
|
||||
#
|
||||
# Unless the option is explicitly used, vendored dependencies control is
|
||||
# disabled.
|
||||
#
|
||||
# If you want to disallow all vendored dependencies, put "none" in the approved
|
||||
# dependencies list.
