一、编译

1、
资源下载：easy3d giuhub

2、解压缩

3、用qt打开CMakeLists.txt即可


4、点击项目，选择debug或者release，图中3处可自行选择，因为我的qt版本是6，easy3d默认是5，所以qt我没有配置编译

5、先点击执行cmake,在点击构建，即可生成lib和dll文件，同样的方法构建一下release版本，生成如下：

6、把源文件中如下拷贝进include文件即可，最终如下：


bin

lib

include

7、环境变量添加bin路径

二、配置

1、新建立一个qt qmake应用
pro文件添加

注

如果习惯用cmake的，参照这些教程即可学习，难度不大
