> find another way to coerce cmake into producing working results on OSX Are you sure that results actually "do no not work" on OS X (and that this has nothing to do with QStandardPaths returning unexpected locations)?! It is always possible to ensure that the plugins get the correct install_name and even a compatibility_version if there's any point in that (do these get versioning under Linux?). This can be done during the link step but also afterwards (probably more complicated to get right in CMake scripts). Whatever the approach, it should be possible to do it in the CMake macro (cmake already generates an option to set the install_name because otherwise the linker would either assume a relative install_name [just the filename] or use the full path to the output file). I presume that at least some of the plugins targeted here exists for KDE4 and if so, are still built the way they were there? - René J.V. ----------------------------------------------------------- This is an automatically generated e-mail.
