CMake and JSON

[TinyRobby]

I just need some help putting json in my cmake project

[nlohmann]

https://json.nlohmann.me/integration/cmake/

[tomokit0811]

I failed with "External" described in https://json.nlohmann.me/integration/cmake/:

cmake_minimum_required(VERSION 3.1)
project(ExampleProject LANGUAGES CXX)

find_package(nlohmann_json 3.11.2 REQUIRED)

add_executable(example example.cpp)
target_link_libraries(example PRIVATE nlohmann_json::nlohmann_json)

Because the nlohman-json is the header-only library, it may require another manner.
I succussed with the following way:

find_package(nlohmann_json REQUIRED)
if(nlohmann_json_FOUND)
  include_directories(${nlohmann_json_INCLUDE_DIRS})
else()
  message(STATUS "nlohmann_json NOT Found !")
endif(nlohmann_json_FOUND)

I'm glad if this would help TinyRobby.
