如何修复 OpenGL Superbible 第 6 版书提供的 CMake 文件

Question

我在编译OpenGL Superbible, 6th ed 提供的示例代码时遇到问题。我正在使用 Ubuntu 19.04 和 CMake 3.13.4。我拥有所有必要的依赖项。 CMake 执行没有问题（“cmake .”），但是当我输入 make 命令时它失败了。

我的印象是它与 GLFW 有关，但我不知道如何更改 CMake 以使其正常工作。

这是示例代码的链接。 https://github.com/openglsuperbible/sb6code

我已经在 CMakeLists.txt 文件的第 13 行修复了这个问题，但它仍然没有编译。

发件人：

if(WIN32)
set(COMMON_LIBS sb6 optimized GLFW_r32 debug GLFW_d32)
elif (UNIX)
set(COMMON_LIBS sb6 glfw ${GLFW_LIBRARIES} GL rt dl)
else()
set(COMMON_LIBS sb6)

收件人：

if(WIN32)
set(COMMON_LIBS sb6 optimized GLFW_r32 debug GLFW_d32)
else()
set(COMMON_LIBS sb6 glfw ${GLFW_LIBRARIES} GL rt dl)

我已经尝试将 find_package(glfw3 3.2 REQUIRED) 添加到文件的开头，但仍然没有成功。

这是我当前的 CMakeLists.txt：

编辑：运行“make V=1”虽然我看不到任何其他信息。

我已更改代码和 cmake 文件以使用 GLFW3。现在项目编译并运行。我在这里上传到github：https://github.com/mlioz/sb6code_fixed
