Unity官方文档对于Mesh.bindposes的解释比较含糊，比较难以理解其含义，在这我用人话解释下。
Mesh.bindposes是一个数组，每个元素是Matrix4x4对象，是对应骨骼初始形变的逆变换，可以消除骨骼初始的形变，这样在骨骼动画里面可以用来实时计算骨骼的形变增量，然后通过骨骼权重把对应的形变作用到顶点上。
对于这个逆变换，官方的示例看起来比较抽象
bindPoses[1] = bones[1].worldToLocalMatrix * transform.localToWorldMatrix;要理解这行代码，可以做下简单推导
For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.
After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
