GNU Radio Radar Toolbox

I am trying to download the GNU Radio Radar Toolbox from this link(https://github.com/kit-cel/gr-radar). I followed the steps listed in that link, but when I reach the {cmake ../} it gives that:

-- Checking for module 'gmp'
--   No package 'gmp' found

and

-- Checking for module 'Qt5Qwt6'
--   No package 'Qt5Qwt6' found

When I started searching how to download the Qt, I noticed that is not free. Also, some of the online commands (shown below) don't solve the problem.

sudo apt-get install qt5-default
sudo apt-get install qt5-doc
sudo apt-get install qt5-doc-html qtbase5-doc-html
sudo apt-get install qtbase5-examples

Any idea how to solve the problem of these two packages?

To build GNU Radio Radar Toolbox on Ubuntu 18.04.6 LTS you have install GRC 3.8 from GNU Radio PPA and the build-dependencies by

sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.8
sudo apt-get update
sudo apt-get install git cmake build-essential gnuradio-dev qtbase5-dev libuhd-dev doxygen graphviz swig libqwt-qt5-dev texlive-latex-base texlive-binaries

and then compile using the following commands

cd ~/Downloads
git clone https://github.com/kit-cel/gr-radar.git
cd gr-radar
mkdir build
cd build
cmake ..
make -j$(nproc)

sudo ./../examples/setup/setup_core
ctest
sudo make install
