This repository is meant to serve as an example of how to use simdjson as a CMake dependency by having simdjson as a git submodule. It is not the most efficient approach, read on for faster approaches.
Usage:
mkdir build && cd build && cmake .. && cmake --build . && ./src/test
The simple CMake project builds a simple parser (./src/test) which can parse a given JSON document (provided as a command-line parameter) and determine whether it is valid JSON.
Please refer to the main simdjson project for further documentation.
Fundamentally, it is as simple as adding the following line after copying the project as a subdirectory in your own project:
add_subdirectory(simdjson EXCLUDE_FROM_ALL)
If your own project is under git, you probably do not want to copy simdjson in your own git repository. Instead, you want to add it as a submodule.
Once you have a git repository, adding simdjson as a submodule is relatively easy, type:
git submodule add https://github.com/simdjson/simdjson.git
Using submodules, you can control exactly which version your colleagues are using, down to the commit. Furthermore, submodules are portable: they work wherever git works.
Then you can just follow our example.
We can also do a demo using a single CMakeLists.txt file.
Users who prefer to use CMake's ExternalProject approach may refer to our example.
