Bulld not working on Mac due to error in "glad.h"

[RainerXE]

To follow standard via "install-macos.h." The following error showed up at the gcc command: "In file included from vendor/glad/src/glad.c:25: vendor/glad/src/../include/glad/glad.h:89:10: fatal error: 'KHR/khrplatform.h' file not found 89 | #include <KHR/khrplatform.h>"

I fixed it by changing the glad.h file line 89 from: "#include </KHR/khrplatform.h>" to "#include <../KHR/khrplatform.h>

Hope this helps for others.

Rainer PS: I have also attached the corrected file. glad.h.zip

I guess it will not work because this : https://github.com/cococry/runara/issues/1

no error report, but text not show inside window.

this is my opengl 4.1 patch, it work for windows. (macOS not show text)
