Scripts are copied from libosmium 2.14.0. The protobuf script will properly check for the headers and allow to include an external version. Require libosmium 2.14 because of the external protobuf library.

|
|
# 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()
