Question

我最近使用macports升级了我在我的项目（glfw-devel）中使用的库，现在我的可执行文件与lib/libglfw.3.dylib而不是opt/local/lib/libglfw.3.dylib动态链接，这是lib的实际位置所以我收到dyld: Library not loaded错误。

我知道如何使用install-names或使用简单副本解决此问题。然而，我无法理解的是，为什么在简单升级后会突然发生这种情况。我没有更改CMakeLists.txt中的任何内容（下面最相关的部分），我使用的所有其他库都有正确的路径。请注意，文件中没有我引用lib/的地方。

这可能是与macports相关的问题吗？如何确保我的未来二进制文件将使用正确的路径进行编译？

我遇到了同样的问题。我花了好几个小时来搞清楚。原来，这个问题是glfw版本所关注的。 glfw 3.1版还可以。试试吧。

或者该错误已发布在Macports错误列表中：glfw @3.2: install_name is not set properly

macports，cmake / make和'dyld：库没有加载'
