Qt4 to Qt5 libraries

[younguns]

Was trying to compile makemkv, and get this error:
checking for qt5... no
configure: error: Qt library (version 5) is required to build GUI

Was following the install instructions on the board for Linux, and it shows to do this:
sudo apt-get install build-essential pkg-config libc6-dev libssl-dev libexpat1-dev libavcodec-dev libgl1-mesa-dev libqt4-dev zlib1g-dev

So done that, and and all the ffmpeg compiling, but as you can see Qt5 is not mentioned in this instructable at all.
It shows to install libqt4-dev. I need the equivalent for Qt5 now.

Any help?

This topic can be deleted now.
I see the Linux install information has been changed now.
Thanks!
