First you should verify what files have been installed in $INSTALL_PREFIX/lib/cmake/plplot/ by your PLplot install step, where $INSTALL_PREFIX is the installation prefix you chose for PLplot. Here is an example of what those files are named on Linux: software@raven> ls /home/software/plplot/installcmake/lib/cmake/plplot/ export_plplot-noconfig.cmake export_plplot.cmake plplotConfig.cmake where "/home/software/plplot/installcmake" happens to be the install prefix I have chosen. Assuming those files have been installed correctly there, then the final step is to give a hint to CMake about where they are located. Normally, I find putting $INSTALL_PREFIX/bin on my PATH environment variable is enough, but look at the cmake help for find_package to look for other environment variables you could set. > Is it possible to set this variable in PLplot CMakeLists.txt install? PLPLOT_HOME is an ancient leftover from proprietary Unix days, and is sometimes still useful if you are doing everything by hand. But you should ignore it for this case where you are using CMake facilities to find PLplot. > Is it possible to set env PATH in PLplot CMakeLists.txt to add program > files/plplot/bin? No, it is probably not a good idea to have the official PLplot installation set environment variables. Instead, that is something each user of the installed PLplot should do for themselves (like I suggested above for the PATH case). Alan __________________________ Alan W.
