Subject: [PATCH] deps/glad: Fix build with GCC-10

​

GCC-10 defaults to '-fno-common' [1], which triggers issues with

defining global variables multiple times.  To fix the build, use

'extern' to turn the first definition of 'gladGetProcAddressPtr'

into a declaration.

Closes https://github.com/obsproject/obs-studio/issues/2828
