From f6566338ebd6559b0fbe61e1557ee735bf58dcdd Mon Sep 17 00:00:00 2001 From: ameerj <52414509+ameerj@users.noreply.github.com> Date: Sat, 13 Feb 2021 15:52:21 -0500 Subject: host_shaders: Modify shader cmake integration to allow for larger shaders using a raw string to encapsulate the entire shader code limits us to shaders of size less than 2KB.
