GLFW + CMake + Clion 许多未定义的参考

Question

在此处完成 CMake Noob。我正在尝试在 Clion IDE 中使用 glfw 库，即使经过 2 天的谷歌搜索，我也无法理解我错过了什么/做错了什么。

以下是详细信息：

操作系统：Windows 8 Pro 64 位

IDE：克莱恩

制作工具：CMake

编译器：MinGW v3.21

项目结构：

CMakeList.txt

cmake_minimum_required(VERSION 3.3)
project(openGL)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)

add_executable(openGL ${SOURCE_FILES})

#add_library(A SHARED IMPORTED)
#set_property(TARGET A PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/GLFW/lib-mingw-w64/glfw3.dll)

add_library(B STATIC IMPORTED)
set_property(TARGET B PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/GLFW/lib-mingw-w64/glfw3dll.a)

add_library(C STATIC IMPORTED)
set_property(TARGET C PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/GLFW/lib-mingw-w64/libglfw3.a)

target_link_libraries(openGL B C)

Answer 1

这就是我解决这个头痛的方法：

1. 已下载 32 位 glfw 二进制文件（即使我在 64 位机器上）

2. 从我的项目中的二进制文件中重命名并复制粘贴的选定文件，如下所示：

3. 像这样修改了我的 CMakeLists.txt：

4. 构建并点击运行！

Answer 2

在 CMakeLists.txt 的末尾添加以下内容

find_package(glfw3 REQUIRED )
target_link_libraries(projectname  GL glfw)
