Where to find Examples and compile error

[Chongyao]

Hi! Nice Job. However, I met some problems when I use it.
1.How do I find the HDK examples(toolkit/samples/SOP/SOP_WindingNumber)?

2. I included these files and use the class.When I compile, I meet error of "undefined reference to " memeber function of UT_SolidAngle, which is caused by method of member function written in .cpp file.

1. This GitHub account is a 3D software company, and the software name is Houdini. HDK examples (toolkit/samples/SOP/SOP-WindingNumber) means that you need to install Houdini and find it in the software directory.
2. I am a user of Houdini and a fan of HDK. I can successfully compile and run this code based on HDK Examples. If you need any help, you can contact me.
