Install on Ubuntu 20.04

[rtrepos]

I tried the install commands provided in README.md and I got this error on cmake command.

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake:28 (find_package):
Could not find a package configuration file provided by "Qt5Svg" with any
of the following names:

Qt5SvgConfig.cmake
qt5svg-config.cmake

After I installed libqt5svg5-dev it worked.
