#
|
#This module provides the following imported targets, if found:
|
#
|
#``license_generator::lcc``
|
# The lcc executable

#
|
#If lcc is not found this module will try to download it as a submodule
|
#Git must be installed.
|
#
|
#Input variables
|
#^^^^^^^^^^^^^^^^
|
#
|
#``LCC_LOCATION`` Hint for locating the lcc executable
|
#
|
#Result Variables
|
#^^^^^^^^^^^^^^^^
|
#
|
#This will define the following variables:
|
#
|
#``LCC_FOUND``
|
# True if the system has the Foo library.
|
#``lcc_VERSION``
|
#
|
#Cache Variables
|
#^^^^^^^^^^^^^^^
|
#
|
#The following cache variables will also be set:
