Hello I have problem to make this project due Qt version incompatibility since I have Qt5 installed in my ubuntu previously:

sudo apt-get install libqwt-qt5-dev qtbase5-dev give me:

libqwt-qt5-dev is already the newest version (6.1.4-1.1build1).
qtbase5-dev is already the newest version (5.12.8+dfsg-0ubuntu2.1).

but when make the project I have:

[ 80%] Linking C executable complexplot_test_c
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/9/../../../../lib/libqwt-qt5.so: undefined reference to `qt_version_tag@Qt_5.12'
collect2: error: ld returned 1 exit status
make[2]: *** [test/c/CMakeFiles/complexplot_test_c.dir/build.make:100: test/c/complexplot_test_c] Error 1
make[1]: *** [CMakeFiles/Makefile2:218: test/c/CMakeFiles/complexplot_test_c.dir/all] Error 2
make: *** [Makefile:139: all] Error 2

this error is related with version incompatibility?.

Maybe could I modify any file for make it compatible...

thanks.
