# FindXdgScreensaver
|
|
# ------------
|
|
#
|
|
# Try to find the xdg-screensaver executable
|
|
#
|
|
# This will define the following variables:
|
|
#
|
|
# ``XdgScreensaver_FOUND``
|
|
# True if (the requested version of) XdgScreensaver is available
|
|
#
|
|
# ``XdgScreensaver_VERSION``
|
|
# The version of XdgScreensaver
|
|
#
|
|
# ``XdgScreensaver_EXECUTABLE``
|
|
# The xdg-screensaver executable
|
|
#
|
|
# If ``XdgScreensaver_FOUND`` is TRUE, it will also define the following imported
|
|
# target:
|
|
#
|
|
# ``XdgScreensaver::XdgScreensaver``
|
|
# The xdg-screensaver executable
