麻烦尝试构建opengl superbible示例代码 [英] trouble trying to build opengl superbible example code

问题描述

所以我得到了超级第六版，我试图cmake和做示例代码框架，但得到这个错误：

So I got the superbible 6th edition, and am trying to cmake and make the example code framework, but get this error:

推荐答案

在第13行的CMakeLists.txt中有一个错误
（ https://github.com/openglsuperbible/sb6code/blob/master/CMakeLists。 txt ）

There is a bug in CMakeLists.txt at line 13. (https://github.com/openglsuperbible/sb6code/blob/master/CMakeLists.txt)

将elif（UNIX）更改为elseif（UNIX），即可。

Change "elif (UNIX)" to "elseif (UNIX)",and it will be ok.
