找不到Glog (缺少: GLOG_INCLUDE_DIR GLOG_LIBRARY)

Question

我正在尝试使用CMAKE在Ubuntu 20.04中安装openpose，我得到了以下错误：

Could NOT find Glog (missing: GLOG_INCLUDE_DIR GLOG_LIBRARY) 

我遵循了这里的说明(不幸的是，屏幕截图不可用，但我只是遵循了文本命令)：https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation/README.md

我在openpose文件夹中创建了一个build文件夹，然后运行cmake-gui ..命令。

将打开GUI，并选中所有这些选项(我不更改任何内容)：

​

错误是：

然后，我使用sudo apt-get install libgflags-dev命令安装了gflag，但仍然得到相同的错误。我该如何解决这个问题呢？

这是用于查看我在哪个版本的存储库中重现错误的git log：

Answer 1

$ sudo apt install libgoogle-glog-dev 

另外，

$ sudo apt-get install libgflags-dev
$ sudo apt install libgoogle-glog-dev
$ sudo apt-get install protobuf-compiler libprotobuf-dev

因为最初我没有安装其中任何一个。

Answer 2

如果你是从命令行运行的，你应该已经看到它们了…

 if (NOT GLOG_FOUND)
    message(FATAL_ERROR "Glog not found. Install Glog from the command line using the command(s) -\
      sudo apt-get install libgoogle-glog-dev")
  endif (NOT GLOG_FOUND)

  if (NOT GFLAGS_FOUND)
    message(FATAL_ERROR "GFlags not found. Install GFlags from the command line using the command(s) --\
      sudo apt-get install libgflags-dev")
  endif (NOT GFLAGS_FOUND)

  if (NOT OpenCV_FOUND)
    message(FATAL_ERROR "OpenCV not found. Install OpenCV from the command line using the command(s) --\
      sudo apt-get install libopencv-dev")
  endif (NOT OpenCV_FOUND)

注意:一个更好的方法是在第三方不存在的时候使用FetchContent() (因为他们提供了基于CMake的构建)，而且提供的命令也只是ubuntu...
