Edit: /srv/osrm/osrm-backend/third_party/libosmium/cmake/FindOsmium.cmake (13638B)

#----------------------------------------------------------------------
#
#  FindOsmium.cmake
#
#  Find the Libosmium headers and, optionally, several components needed
#  for different Libosmium functions.
#
#----------------------------------------------------------------------
#
#  Usage:
#
#    Copy this file somewhere into your project directory, where cmake can
#    find it. Usually this will be a directory called "cmake" which you can
#    add to the CMake module search path with the following line in your
#    CMakeLists.txt:
#
#      list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
#
#    Then add the following in your CMakeLists.txt:
#
#      find_package(Osmium [version] REQUIRED COMPONENTS <XXX>)
#      include_directories(SYSTEM ${OSMIUM_INCLUDE_DIRS})
#
#    The version number is optional. If it is not set, any version of
#    libosmium will do.
#
#    For the <XXX> substitute a space separated list of one or more of the
#    following components:
#
#      pbf        - include libraries needed for PBF input and output
#      xml        - include libraries needed for XML input and output
#      io         - include libraries needed for any type of input/output
#      geos       - include if you want to use any of the GEOS functions
#      gdal       - include if you want to use any of the OGR functions
#      proj       - include if you want to use any of the Proj.4 functions
#      sparsehash - include if you use the sparsehash index (deprecated!)
#      lz4        - include support for LZ4 compression of PBF files
#
#    You can check for success with something like this:
#
#      if(NOT OSMIUM_FOUND)
#          message(WARNING "Libosmium not found!\n")
#      endif()
#

#

#    OSMIUM_INCLUDE_DIRS  - Where to find include files.
#    OSMIUM_XML_LIBRARIES - Libraries needed for XML I/O.
#    OSMIUM_PBF_LIBRARIES - Libraries needed for PBF I/O.
#    OSMIUM_IO_LIBRARIES  - Libraries needed for XML or PBF I/O.
#    OSMIUM_LIBRARIES     - All libraries Osmium uses somewhere.
