This repository is not more useful. Indeed, since v3.11.3, you can use:

include(FetchContent)

FetchContent_Declare(json URL https://github.com/nlohmann/json/releases/download/v3.11.3/json.tar.xz)
FetchContent_MakeAvailable(json)

target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)

Release-tracking repository for nlohmann/json

Goal is to provide a lightweight and autonomous repository tracking every releases of nlohmann/json.

It is meant to be used with CMake FetchContent.

You can always replace the URL by the official repository: https://github.com/nlohmann/json. The only differences are:

• The download size: ~500KB vs ~150MB (300× difference)
• Some options are not available. See the unsupported options section.

Example

include(FetchContent)

# Optional: set this to ON if your target publicly links to nlohmann_json and needs to install() 
# set(JSON_Install ON)

FetchContent_Declare(json
  GIT_REPOSITORY https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent
  GIT_PROGRESS TRUE  GIT_SHALLOW TRUE
  GIT_TAG v3.11.2)

FetchContent_MakeAvailable(json)

target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)

Unsupported options

The following options are currently not supported. This is done on purpose because they do not really make sense for a mirror repository, or they have not been thoroughly tested. Consider using the official repository if you need these options.

• JSON_CI
• JSON_BuildTests

Updates

This repository is fully autonomous. It updates itself every week using github actions.
