C ++ second day beginner.
I wanted to run the sample program below and started touching C ++.

Thanks for your patience, but I hope you can forgive me even if this is a rudimentary question because I don't have enough understanding of C ++ basics and projects/libraries.

Environment
Windows10 Pro
VS Code

Error message

After installing MinGW and confirming that "gcc -v" passes,
The above sample code is clone, and c_cpp_properties.json is described as follows

When "gcc fisheye.cpp" was executed, an error occurred.

PS C: \ programs \ fisheye-master \ fisheye-master>gcc. \ fisheye \ fisheye.cpp

 #include<GLFW/glfw3.h>
          ^ ~~~~~~~~~~~~~
compilation terminated.

Since "glfw3.h" exists under "C:/programs/fisheye-master/fisheye-master/libs/include/GLFW", we are struggling without knowing the reason.

-Install GLFW (recompiled) to another path and add that path to include path.
・ Rebuilding environment, re-clone sample program
→ Neither of them changed to an error.

Supplemental information

Although it is not supplemental information, "Hello World!" can be output to the console.
I think that there is no mistake in the most basic environment construction itself.

Thanks for your cooperation.
