现在我不知道如何实现这一点。如何构建此项目？

std:：enable\u如果只在C++14中引入了\u t

，那么您应该将所需的标准设置为C++14：

set(CMAKE_CXX_STANDARD 14)

---

您是否尝试将

-std=c++11

添加到您的CMake标志中？嗨，Chiel，我对CMake比较陌生。您能告诉我应该在CMake文件中的何处添加此行吗？我尝试了

设置（CMake_CXX_标志-std=c++11）

但是给了我同样的

std:：enable_if_t

错误。您好，谢谢。这解决了大多数问题。但我仍然收到这个错误。它是否有某种关联？

错误：命名空间中的COpenGLScenePtr mrpt:：opengl没有命名类型opengl:：COpenGLScenePtr scene

@MJ192似乎没有关联。
