cmake_minimum_required(VERSION 2.8.8)
#
# The KenLM cmake files make use of add_library(... OBJECTS ...)
#
# This syntax allows grouping of source files when compiling
# (effectively creating "fake" libraries based on source subdirs).
#
# This syntax was only added in cmake version 2.8.8
#
# see http://www.cmake.org/Wiki/CMake/Tutorials/Object_Library
# This CMake file was created by Lane Schwartz <dowobeha@gmail.com>
# Explicitly list the source files for this subdirectory
#
# If you add any source files to this subdirectory
# that should be included in the kenlm library,
# (this excludes any unit test files)
# you should add them to the following list:
#
# Because we do not set PARENT_SCOPE in the following definition,
# CMake files in the parent directory won't be able to access this variable.
