cd cmake-3.18.3 mkdir build cd build ../bootstrap && make && sudo make install
cd plplot-5.15.0 mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/usr/local ../ >& cmake.out make make install cd .. rm -r -f build (to avoid multiple instances of plplot-fortran.pc, etc) sudo updatedb (so configure calls to locate can find *.pc files etc)NOTE: The jpeg driver was not available, so a work-a-round is to manually reply with SVG when programs like BPLT pause. Clearly, there is room for improvement with CENTOS 8. No problems like this with CENTOS 7 or other operating systems like Debian 10.
