cd ~

cd SerialTest
mkdir build && cd build

You need to download QCustomPlot archive, extract the qcustomplot.cpp and qcustomplot.h in the /src folder(replace the existing qcustomplot.h), then build.

wget https://www.qcustomplot.com/release/2.1.1/QCustomPlot-source.tar.gz
tar -xzf QCustomPlot-source.tar.gz
cp qcustomplot-source/qcustomplot.* ../src

If the qcustomplot.cpp doesn't exist in the src/ folder, the qmake will try to find the library file(xxx.so/xxx.dll) in the building directory(where you call the qmake command) and the default library directory.

export QT_SELECT=qt5
qmake ../src
make -j4 && make clean
./SerialTest
