为 CentOS 7 构建 OpenGL SuperBible 7，缺少 glfw3
Building OpenGL SuperBible 7 for CentOS 7, missing glfw3
问题
我正在使用 CentOS 7 并一直在尝试更正构建说明的问题，尤其是在尝试查找 glfw 库时。按照 HOWTOBUILD.txt 文件（可从 SB7 git 存储库获得）的说明，当 运行 make 时，我经常收到错误消息命令：
[sweet_ass_user_name@bitchin_camaro build]$ make

make: *** [all] Error 2
为了让事情更混乱，我已经安装了这些包：
- glfw
- glfw-devel
当检查我安装的 glfw 包时，rpm -qa | grep glfw，我的系统 returns:
glfw-3.2.1-2.el7.x86_64
glfw-devel-3.2.1-2.el7.x86_64
很明显，安装的 glfw 库是 glfw 库的第 3 版。
可是，为什么系统不识别？

答案
事实证明，由于有关 glfw 包 和 glfw 版本 之间差异的命名问题令人困惑，答案很简单修改 CMakeLists.txt 文件（link 此处：SB7 CMakeLists.txt）
第 28 行需要删除一个字符。将 glfw3 更改为 glfw.
但是！！
也不要重命名上面那行的 glfw3 名称。我只能假设这是指 glfw3 的版本，而不是包的名称。
现在，代码构建和所有构建 运行 都很好。
补充说明
对于 centos7 系统，为了使用 CUDA 的当前构建规则，您需要 运行 cmake3 ..（而不是 cmake）
固定代码
cmake_minimum_required (VERSION 2.6)
project (superbible7)
LINK_DIRECTORIES( ${CMAKE_SOURCE_DIR}/lib )
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
