I started the building with the following line: cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gfortran_plplot595 -DBUILD_TEST=ON -DCMAKE_VERBOSE_MAKEFILE=ON -DENABLE_DYNDRIVERS=OFF -DBUILD_SHARED_LIBS=OFF -DENABLE_octave=OFF -DPLD_plmeta=ON ~/svn_work/programming/plplot/plplot-5.9.5
The main point is that it is done in the external build-directory prior to installation with setting -DBUILD_TEST=ON. If I follow the wiki http://www.miscdebris.net/plplot_wiki/index.php?title=Testing_PLplot then the compilation and linking works ok (actually both are done with one command, the object file is not built separately).
