include problem, when cmake on osx

[xiazhibin]

I clone the project , and make install.
In my cpp file, I must #include "nlohmann/json.hpp" not #include "json.hpp" as it mentions

Why?

This is due the latest changes in the CMakeLists.txt to be consistent with the projects name and namespace. Also to avoid polute a systems include folder when other libraries might have a json.hpp as well.

And for full consistency, the develop-branch is preparing version 3.0.0 which will bring breaking changes as well.
If you do not need special features from the current develop-branch it might be advised for you to use the master branch as the lates stable release.

Nonetheless it might be an option to enable when running cmake && make install to define if it should be in a subfolder or not.
