I managed to install ccViewer, but while running i am getting below error.

INTERESTINGLY, I LOOKED AT THE FOLDER /usr/lib/x86_64-linux-gnu, and all the files are available already.

lrwxrwxrwx 1 root root 21 May 13 2017 /usr/lib/x86_64-linux-gnu/libQt5OpenGL.so.5 -> libQt5OpenGL.so.5.5.1
lrwxrwxrwx 1 root root 18 May 13 2017 /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 -> libQt5Gui.so.5.5.1
lrwxrwxrwx 1 root root 19 May 13 2017 /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 -> libQt5Core.so.5.5.1
lrwxrwxrwx 1 root root 22 May 13 2017 /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 -> libQt5Widgets.so.5.5.1


WHEN FILES ARE STILL AVAILABLE, WHY IT IS SHOUTING AT ME SAYING IT DOESN'T FIND FILE? KINDLY HELP.

I'm not a Linux guru, but I remember that you add to call a command at least once to declare the .so files so that they can be found when running CloudCompare. Sadly I can't remember what the command was exactly, and they it doesn't seem to be explained anymore in the newest build instructions (https://github.com/CloudCompare/CloudCo ... r/BUILD.md).

Hopefully a Linux guru can answer ;)
