# Code taken from LDC – the LLVM-based D Compiler

#
# - Find LLVM headers and libraries.
# This module locates LLVM and adapts the llvm-config output for use with
# CMake.
#
# A given list of COMPONENTS is passed to llvm-config.
#
# The following variables are defined:
# LLVM_FOUND - true if LLVM was found
# LLVM_CXXFLAGS - C++ compiler flags for files that include LLVM headers.
# LLVM_ENABLE_ASSERTIONS - Whether LLVM was built with enabled assertions (ON/OFF).
# LLVM_INCLUDE_DIRS - Directory containing LLVM include files.
# LLVM_IS_SHARED - Whether LLVM is going to be linked dynamically (ON) or statically (OFF).
# LLVM_LDFLAGS - Linker flags to add when linking against LLVM
# (includes -LLLVM_LIBRARY_DIRS).
# LLVM_LIBRARIES - Full paths to the library files to link against.
# LLVM_LIBRARY_DIRS - Directory containing LLVM libraries.
# LLVM_NATIVE_ARCH - Backend corresponding to LLVM_HOST_TARGET, e.g.,
# X86 for x86_64 and i686 hosts.
# LLVM_ROOT_DIR - The root directory of the LLVM installation.
# llvm-config is searched for in ${LLVM_ROOT_DIR}/bin.
# LLVM_TARGETS_TO_BUILD - List of built LLVM targets.
# LLVM_VERSION_MAJOR - Major version of LLVM.
# LLVM_VERSION_MINOR - Minor version of LLVM.
# LLVM_VERSION_STRING - Full LLVM version string (e.g. 6.0.0svn).
# LLVM_VERSION_BASE_STRING - Base LLVM version string without git/svn suffix (e.g. 6.0.0).
#
# Note: The variable names were chosen in conformance with the offical CMake
# guidelines, see ${CMAKE_ROOT}/Modules/readme.txt.

# Try suffixed versions to pick up the newest LLVM install available on Debian
# derivatives.
# We also want an user-specified LLVM_ROOT_DIR to take precedence over the
# system default locations such as /usr/local/bin. Executing find_program()
# multiples times is the approach recommended in the docs.
