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:
#
# In order to set correct paths to these files
#    in case this variable is referenced by CMake files in the parent directory,
#    we prefix all files with ${CMAKE_CURRENT_SOURCE_DIR}.
