Problem when building Tellico 4.0.1 on Ubuntu

[Sven Linux]

I am trying to build tellico 4.0.1 on Ubuntu 20.04.6 LTS and after
installing several packages I am getting the following build error when I
run cmake:

cmake .. -DCMAKE_INSTALL_PREFIX=`kf5-config --prefix`

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
CMake Error at CMakeLists.txt:71 (find_package):
  Could not find a package configuration file provided by "Qt" (requested
  version 5.12.0) with any of the following names:

    QtConfig.cmake
    qt-config.cmake

  Add the installation prefix of "Qt" to CMAKE_PREFIX_PATH or set "Qt_DIR"
to
  a directory containing one of the above files.  If "Qt" provides a
separate
  development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred!

I installed qtbase5-dev and there is a Qt5Config.cmake file present now

/usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake

But obviously this does not satisfy the requirement for QtConfig.cmake

Any ideas or suggestions?
