Why can't I connect the library nlohmann/json?

Hello. Somehow fails to connect the library nlohmann/json
In the header file and in the file *.cpp spelled out:
#include <nlohmann json.hpp></nlohmann>
The compilation fails:
In file included from /home/doctor/API/apacheconf.h:7:0,
 from /home/doctor/API/apacheconf.cpp:5:
/usr/local/include/inja.hpp:37:2: error: static assertion failed: nlohmann/json not found.
 static_assert(false, "nlohmann/json not found.");
