Open source JSON parsers are available for in a variety of languages; a popular library in C++ is JsonCpp. In TubeTK, we want to use this standardized format more extensively to configure complex algorithms for reproducible analysis, etc.
Since TubeTK is primarily written in C++ and uses CMake for its build system, we created a CMake configuration for JsonCpp. This also makes the project easier to use as a CMake ExternalProject. The newly created jsoncpp-cmake repository can be downloaded with Git: enjoy!
