# - Find jsoncpp - Overarching find module
# This is a over-arching find module to find older jsoncpp versions and those sadly built
# without JSONCPP_WITH_CMAKE_PACKAGE=ON, as well as those built with the cmake config file.
# It also wraps the different versions of the module.
#
# On CMake 3.0 and newer:
# JsonCpp::JsonCpp - Imported target (possibly an interface/alias) to use:
# if anything is populated, this is. If both shared and static are found, then
# this will be the static version on DLL platforms and shared on non-DLL platforms.
# JsonCpp::JsonCppShared - Imported target (possibly an interface/alias) for a
# shared library version.
# JsonCpp::JsonCppStatic - Imported target (possibly an interface/alias) for a
# static library version.
#
# On all CMake versions: (Note that on CMake 2.8.10 and earlier, you may need to use JSONCPP_INCLUDE_DIRS)
# JSONCPP_LIBRARY - wraps JsonCpp::JsonCpp or equiv.
# JSONCPP_LIBRARY_IS_SHARED - if we know for sure JSONCPP_LIBRARY is shared, this is true-ish. We try to "un-set" it if we don't know one way or another.
# JSONCPP_LIBRARY_SHARED - wraps JsonCpp::JsonCppShared or equiv.
# JSONCPP_LIBRARY_STATIC - wraps JsonCpp::JsonCppStatic or equiv.
# JSONCPP_INCLUDE_DIRS - Include directories - should (generally?) not needed if you require CMake 2.8.11+ since it handles target include directories.
#
# JSONCPP_FOUND - True if JsonCpp was found.
