In Linux I installed from scratch on top of Ubuntu MATE 20.04.

Previous requirements:
gcc
Qt 5.15.2 
OpenGL dev
cmake
git

Install llvm-dev 11 and clang-dev 11
 
Always use your Qt5 path where required:

git clone https://github.com/mcristg/smokegen
cd smokegen
mkdir build 
cd build

cmake -DCMAKE_INSTALL_PREFIX=/usr/local \
      -DLLVM_DIR="/usr/lib/llvm-11/cmake" \
      -DQt5_DIR="~/Qt/5.15.2/gcc_64/lib/cmake/Qt5" \
      -G "Unix Makefiles" ../
make 
sudo make install

cd ../../

git clone https://github.com/mcristg/smokeqt
cd smokeqt
mkdir build 
cd build

cmake -DCMAKE_INSTALL_PREFIX=/usr/local \
      -DQt5_DIR="~/Qt/5.15.2/gcc_64/lib/cmake/Qt5" \
      -G "Unix Makefiles" ../

make

Correct any errors that appear, see files in commonqt/Instructions: 

manual-modification-smokeqtcore.txt
 
sudo make install

cd ../../

git clone -b commonqt5 https://github.com/mcristg/commonqt

cd commonqt

export PATH=$PATH:~/Qt/5.15.2/gcc_64/bin

mkdir build
cd build

cmake -DCMAKE_INSTALL_PREFIX=/usr/local \
      -DCMAKE_PREFIX_PATH=~/Qt/5.15.2/gcc_64 \
      -DSMOKE_LIB=/usr/local \
      -DQt5_DIR=~/Qt/5.15.2/gcc_64/lib/cmake/Qt5 \
      -G "Unix Makefiles" ../

make
sudo make install

In the terminal (your Qt5 path)
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/your path/Qt/5.15.2/gcc_64/lib

or in /etc 
create qt5_lib.conf to add the path to qt5 lib with the following 2 lines (your Qt5 path)

include /etc/ld.so.conf.d/*.conf
/your path/Qt/5.15.0/gcc_64/lib

and then run:
sudo ldconfig

Test commonqt5.
