Fatal error with jsoncpp while compiling for Darwin

I am facing the exact same error as this but for mac os

Error message looks like this:

myfile.cpp:12:10: fatal error: json/json.h: No such file or directory

initially I was trying to run it like this:

g++-11 myfile.cpp -o myfile -ljsoncpp

then I changed it to this:

g++-11 -L/usr/local/opt/jsoncpp myfile.cpp -o myfile -ljsoncpp

and then to this:

g++-11 -I/usr/local/opt/jsoncpp/include -L/usr/local/opt/jsoncpp myfile.cpp -o myfile -ljsoncpp

and then to this:

g++-11 -I./json -L/usr/local/opt/jsoncpp myfile.cpp -o myfile -ljsoncpp

and then to this:

g++-11 -I/path/to/current/dir/json -L/usr/local/opt/jsoncpp pingpong.cpp -o pingpong -ljsoncpp

myfile.cpp was like this intitally:

#include <json/json.h>
...

then influenced by this post I changed it to this:

#include <jsoncpp/json/json.h>
...

but no matter what I do I seem to get the same error

This:

find /usr -name json.h | grep -f json/
Doesnt return anything.

PS: The path of jsoncpp that I used is what I got from this:

brew info jsoncpp

brew --prefix jsoncpp

/usr/local/opt/jsoncpp

-I/opt/homebrew/include is the include directory for #include <json/json.h>.

-L/opt/homebrew/lib is the library directory for -ljsoncpp.

The include and the library paths are valid for the most of homebrew packages.

/opt/homebrew/opt/jsoncpp is the install directory.

You could install brew install pkg-config. Then the compiler and the linker flags can be retrieved:

$ pkg-config jsoncpp --cflags --libs
-I/opt/homebrew/Cellar/jsoncpp/1.9.5/include -L/opt/homebrew/Cellar/jsoncpp/1.9.5/lib -ljsoncpp

And the build command:

$ g++-11 myfile.cpp -o myfile `pkg-config jsoncpp --cflags --libs`

As @RetiredNinja pointed out converting #include <json/json.h> to #include "json/json.h" did the trick.
