[Scons-users] Mesa3D graphics library build failure when using Scons 3.0.3 and newer on Windows with Visual Studio 2017, Scons 3.0.1 is unaffected.

[Bill Deegan]

nir_opcodes.h and any other file which are not present when needed are
indeed relevant.
They indicate what in the build logic is missing dependencies.
If the dependencies were correct, then those files would be created/present
before any file which depends on them is compiled..
