C++ GLFW&x2B；CMake+；许多未定义的引用

在这里完成CMake Noob。我试图在Clion IDE中使用glfw库，即使在谷歌搜索了2天后，我也无法理解我遗漏了什么/做错了什么

详情如下:

操作系统：Windows 8 Pro 64位

IDE:Clion

制作工具：CMake

编者：MingWv3.21

这就是我解决头痛的方法：

下载了32位glfw二进制文件（即使我在64位机器上）

重命名并从我的项目中的二进制文件复制粘贴的选定文件，如下所示：

将my CMakeLists.txt修改如下：

建立和击中运行

在CMakeLists.txt的末尾添加以下内容

find_package(glfw3 REQUIRED )
target_link_libraries(projectname  GL glfw)

您正在尝试链接处于生成状态的

GLFW

库（正如您在

GLFW

子目录下有

Makefile

文件一样）。那里的文件处于某种中间状态，您无法猜测它们的正确用法。相反，您应该在某处安装GLFW库，然后链接已安装的文件。查找已安装软件包的文件最常用的方法是。顺便说一句，任何关于cmake和GL的教程都会显示

find_package
