Unable to catkin_make face_detector package in computer

[AmirulJ]

Hello!

I would like to try face_detector package on my laptop. I have git clone the https://github.com/wg-perception/people.git in my workspace and run catkin_make. But there are many error regarding to the package. For example:

Could not find a package configuration file provided by "easy_markers" with
  any of the following names:

    easy_markersConfig.cmake
    easy_markers-config.cmake

Checking for module 'orocos-bfl'
--   No package 'orocos-bfl' found
CMake Error at /usr/share/cmake-3.16/Modules/FindPkgConfig.cmake:463 (message):
  A required package was not found

I have try to solve one by one, but the errors are still there. May I know how to solve this? Thank you in advance

You can try with rosdep:

sudo apt-get install python-rosdep
sudo rosdep init
rosdep update
cd ~/catkin_ws
rosdep install --from-paths src --ignore-src -y

Thank you for your suggestion. I would like to ask when I run rosdep install --from-paths src --ignore-src -y ,I got this error:

Package libqt4-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libqt4-dev’ has no installation candidate
ERROR: the following rosdeps failed to install
apt: command [sudo -H apt-get install -y libqt4-dev] failed

How can I solve this problem?

You will have to go through those unmet dependencies on your own system, since only you know what is and isn’t installed
