What is the difference between INCLUDE and SINGLE_INCLUDE?

Hi,

I am new to this repository.

I see it is not header only library as stated in the documentations. I need to download includes.

Could someone describe how and which includes I must reference in my cmake? The reason to ask is because there are simple_include and include folder.

I am referring to this:

Just because there are multiple headers, that doesn't make it not header-only. There is also a single stand-alone header in the single_include directory, along with a forward declaration header.

You can use json.hpp as a stand-alone header, or you can use the CMake support as in https://github.com/nlohmann/json?tab=readme-ov-file#cmake

What @gregmarr would be the difference between the single include and the 3rd party dependencies:

I need writing and reading json files. I am wondering what would be missing if I include only the single header?

Nothing. It's the contents of the include directory combined into a single file.
