# FindProtozero.cmake
#
# 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.
#
#----------------------------------------------------------------------
# find include path
