# The following variables are defined:
#  LLVM_FOUND          - true if LLVM was found
#  LLVM_CXXFLAGS       - C++ compiler flags for files that include LLVM headers.
#  LLVM_HOST_TARGET    - Target triple used to configure LLVM.
#  LLVM_INCLUDE_DIRS   - Directory containing LLVM include files.
#  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_ROOT_DIR       - The root directory of the LLVM installation.
#                        llvm-config is searched for in ${LLVM_ROOT_DIR}/bin.
#  LLVM_VERSION_MAJOR  - Major version of LLVM.
#  LLVM_VERSION_MINOR  - Minor version of LLVM.
#  LLVM_VERSION_STRING - Full LLVM version string (e.g. 2.9).
#
# 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.
