Hi Hazen: I am going to post my reply to your question on list because I believe others will be interested in my answer. The important thing to remember is that the build system for the installed examples runs independently of the build system for the PLplot core build, but core build targets and variables are passed to the installed examples build system using EXPORT of targets, configuration of examples/plplot_configure.cmake_installed_examples.in (which ends up as cmake/modules/plplot_configure.cmake in the installed examples tree), and copying of certain unconfigured key files from the source tree such as examples/CMakeLists.txt_installed_examples and examples/c/CMakeLists.txt_installed_examples_c which end up as CMakeLists.txt and c/CMakeLists.txt in the installed examples tree. Revision 10023 is a fairly useful template for what needs to be done in general to add a build of one particular installed example (qt_example in this case) to this new build system. * The qt target required to build qt_example is EXPORTed from the PLplot core build in drivers/CMakeLists.txt. examples/CMakeLists.txt_installed_examples already implements the import of all such EXPORTed targets into the new build system using the "include(export_plplot)" command. * examples/plplot_configure.cmake_installed_examples.in is modified to configure some additional core CMake variables to be used in the installed examples build system to help build qt_example. * examples/c++/CMakeLists.txt_installed_examples_cxx (which is copied to c/CMakeLists.txt in the installed examples tree ) is modified to do the actual build of qt_example using the targets and CMake variables that are available from the core build as well as anything independent that it needs to do itself. A complication for this qt_example case was I needed access to the qt4_wrap_cpp macro. Thus, as documented in examples/c++/CMakeLists.txt_installed_examples_cxx, I had to find Qt4 all over again to get access to that macro (with some care to make sure it was the same as the Qt4 used in the core version), but normally if you don't need such cmake system macros, you would just pass variables like QT_LIBRARIES directly from the core build without having to determine them all over again with a system Find module. Thanks for your interest in using the new build system for the installed examples to build your new pyqt example. I hope the above general explanation will help you toward that goal. I will take a look at that example this afternoon to see if there is anything more I can say to you (off list) to help you with that specific build. Alan __________________________ Alan W.
