我在《Tracking radar targets with multiplereflection points》找到关于Group tracker (GTRACK) Library的API，但是这个Library以及这些函数的定义我找了很久都没有找到。
第一张图片说：
The tracking algorithm is delivered as a source code and pre-compiled target libraries with a ready-to-build makefile infrastructure.
我要怎样才能阅读tracking algorithm并在此基础上做开发?
please and thanks.
