+#  Find the protozero headers.
+#
+#----------------------------------------------------------------------
+#
+#  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(Protozero [version] [REQUIRED])
+#      include_directories(SYSTEM ${PROTOZERO_INCLUDE_DIR})
+#
+#    The version number is optional. If it is not set, any version of
+#    protozero will do.
+#
+#      if(NOT PROTOZERO_FOUND)
+#          message(WARNING "Protozero not found!\n")
+#      endif()
+#
+#----------------------------------------------------------------------
+#
+#  Variables:
+#
+#    PROTOZERO_FOUND        - True if Protozero was found.
+#    PROTOZERO_INCLUDE_DIR  - Where to find include files.
