Could NOT find Glog (missing: GLOG_INCLUDE_DIR GLOG_LIBRARY)

I am trying to install openpose in Ubuntu 20.04 using CMAKE and I get the following error:

Could NOT find Glog (missing: GLOG_INCLUDE_DIR GLOG_LIBRARY)

I am following the instructions here (unfortunately, the screenshots are not available but I just followed the textual commands): https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation/README.md

I made a build folder in openpose folder and then ran the cmake-gui .. command.

A GUI opens with all these checked (I don't change anything): enter image description here

and the error is:

Then, I installed gflags using sudo apt-get install libgflags-dev command but I still get the same error. How could I fix this problem?

This is the git log to see which version of repo I am at for reproducing the error:

Solution 
  • $ sudo apt install libgoogle-glog-dev

    Also,

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

    since initially I didn't have any of them installed.
