#
# 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
#
# You can check for success with something like this:
#
# if(NOT OSMIUM_FOUND)
# message(WARNING "Libosmium not found!\n")
# endif()
#
#----------------------------------------------------------------------
#
# Variables:
#
# OSMIUM_FOUND - True if Osmium found.
# 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.
#
#----------------------------------------------------------------------
