# - Find LLVM library
# Find the native LLVM includes and library
# This module defines
# LLVM_INCLUDE_DIRS, where to find LLVM.h, Set when LLVM_INCLUDE_DIR is found.
# LLVM_LIBRARIES, libraries to link against to use LLVM.
# LLVM_ROOT_DIR, The base directory to search for LLVM.
# This can also be an environment variable.
# LLVM_FOUND, If false, do not try to use LLVM.
#
# also defined, but not for general use are
# LLVM_LIBRARY, where to find the LLVM library.
