com_github_gflags_gflags does not match the name

Hi, trying to install Seurat I got those errors:

(@com_github_gflags_gflags) does not match the name given in the repository's definition (@gflags)
missing input file '@ion//:gyp-out/win-ninja/opt_x64/tracinghelper.lib'.
ERROR: C:/seurat/seurat/pipeline/BUILD:78:1: //seurat/pipeline:seurat: missing input file '@ion//:gyp-out/win-ninja/opt_x64/tracinghelper.lib'.
C:/seurat/seurat/pipeline/BUILD:78:1 1 input file(s) do not exist.

ERROR: C:/seurat/seurat/pipeline/BUILD:78:1: //seurat/pipeline:seurat: missing input file '@ion//:gyp-out/win-ninja/opt_x64/iongfxutils.lib'.

Could it be because I don't use Visual Studio 2015 update 2?

I don't think the gflags warning is related to the errors that follow it:

missing input file '@ion//:gyp-out/win-ninja/opt_x64/tracinghelper.lib'.

This looks like Ion isn't built or maybe built incompletely. You have to install and build it inside the Seurat repo before you can build Seurat.
