CMake & Submodules Integration¶

sip2json provides full CMake target support with exported target sip2json::sip2json.

Modern CMake Integration via CPM¶

CPM.cmake is the recommended package manager for C++ CMake projects:

cmake_minimum_required(VERSION 3.23)
project(MySipApp LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

include(cmake/CPM.cmake)

CPMAddPackage("gh:SiddiqSoft/sip2json#v1.17.0")

add_executable(MySipApp main.cpp)
target_link_libraries(MySipApp PRIVATE sip2json::sip2json)

CPMAddPackage automatically resolves dependent packages (nlohmann_json and ctre).

FetchContent Integration¶

If you prefer CMake's built-in FetchContent module:

include(FetchContent)

FetchContent_Declare(
    sip2json
    GIT_REPOSITORY https://github.com/SiddiqSoft/sip2json.git
    GIT_TAG        v1.17.0
)
FetchContent_MakeAvailable(sip2json)

target_link_libraries(your_target PRIVATE sip2json::sip2json)
