This build includes the GPU-specific code (EGL, GLES) The armhf_sysroot should be generic enough to support other ARM targets, like the Raspberry Pi. I split out the EGL dependencies into their own CIPD package (chromebook_c100p_lib) to facilitate the modularity of the approach. When we add another ARM chromebook, maybe one that has different libraries, we should be able to re-use armhf_sysroot and then a newly created CIPD asset for that specific GPU (if needed). Maybe this also can be used to build for the chromecasts (thus the TODO) Bug: skia: NOTRY=true Change-Id: Icc131025932dc8d41da5be39f3c5cad0aa95d848 Reviewed-on: https://skia-review.googlesource.com/11064 Commit-Queue: Kevin Lubick <kjlubick@google.com> Reviewed-by: Eric Boren <borenet@google.com>
