libusockets.h: No such file or directory

I am getting the following error when compiling a c++ program with uWebSockets.

I cloned the built the program successfully (with uSockets) as shown:

Here is the compilation error I'm getting.

How can I resolve this?

To summarize, you'd add the path to the directory that contains libusockets.h to the compiler include paths list.

I'm not familiar with Cmake but surely there must be a way to specify -I/wherever/uSockets/lives

Thanks. It worked.
