I am trying to run the main.cpp of the course and for it to run correctly i need to import a vecmath.h. In the original code the vecmath.h is already included but i dont know how to use headers and when i tried apreared the follow message:

tarting build…
g++ -fdiagnostics-color=always -g /home/leticia/OpenGL_works/inicialMIT.cpp /home/leticia/OpenGL_works/glad/.c /home/leticia/OpenGL_works/glad/.h -o /home/leticia/OpenGL_works/inicialMIT -lGL -lglfw -ldl -lX11 -lpthread
/home/leticia/OpenGL_works/inicialMIT.cpp:6:10: fatal error: vecmath.h: No such file or directory
6 | #include <vecmath.h>
| ^~~~~
compilation terminated.

and in my code the correction extension is says that vecmath.h do not exist on the directory. How can i correct this?

I tried putting it in my glad folder and using task making so that everything using header there is compiled.

                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "${workspaceFolder}/glad/*.c",
                "${workspaceFolder}/glad/*.h",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "-lGL",
                "-lglfw",
                "-ldl",
                "-lX11",
                "-lpthread"
            ],

I also tried

                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "${workspaceFolder}/glad/*.c",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "-lGL",
                "-lglfw",
                "-ldl",
                "-lX11",
                "-lpthread",
                "-vecmath.h"

            ],
