【问题描述】：
这是我在这里的第一篇文章。我正在尝试编译 RGBdemo 以测试其使用 kinect 的重建能力。
我已按照这些说明进行操作 RGBdemo compiling instructions
我能够或多或少一致地遵循所有说明，但我在结尾处跺脚（编译 RGBdemo 0.7）。这是制作代码。

虽然我有一些编程技能，但我没有太多编译程序的经验。
我已经广泛搜索了如何解决这个问题，寻找错误 “引用符号 'glOrtho'”和“添加符号：命令行中缺少 DSO”，但我找不到对我有帮助的体面解决方案。
例如这种情况 Linker error : undefined reference to symbol 'glOrtho' 声明我应该将 OpenGL 库链接到某个文件。就我而言，我认为它应该是 main.cpp 但我找不到它:-(。 非常感谢任何帮助。
更新
这是我在制作中能够取得的当前进展

我会尝试找到更正这些目录的方法，但我真的很感谢这方面的一些帮助。拜托，我正在通过反复试验来做这件事，我知道这不是正确的方法。我不是 cmake 编译方面的专家。
【问题讨论】：
-
我在这里保留了我的研究结果。似乎在这个 Github 帖子 github.com/rgbdemo/rgbdemo/issues/27 中也有类似的问题
-
一些进展...通过某种奇迹，我能够发现我必须在 /build/nestk/deps/openni 的 link.txt 文件中添加“-lGL” /Nite/Samples/Boxes/CMakeFiles/Boxes.dir/link.txt 文件。这必须对 Boxes、Players 和 CircleControl 目录进行。每个都有一个 link.txt 文件，该文件必须在“lglut”和“-lusb-1.0”选项之间有那个额外的选项
