【不具合回避】MRTK vNext アルファ版の HoloLens 用ビルドを試してみる

※ これは 2018/08/18 Unity 2018.2.5f1、Mixed Reality Toolkit vNext Alpha v2018.7.0.0 時点の情報です

最新版では動作が異なる可能性がありますのでご注意ください

前回はアルファ版の次世代 Mixed Reality Toolkit で HoloLens にインストールしたところでエラー！

これを何とかしたい

なんか HoloLens に必要なフレームワーク VCLibs が入ってない的なエラーメッセージ

because this package depends on a framework that could not be found. Provide the framework "Microsoft.VCLibs.140.00.Debug"

とりあえず Unity 2018.2.5f1 が出ていたのでアップデートして再度ビルドからやり直し
