Well, in the end it doesn't matter if they use cmake or a hand written build system or what else. In the end you want to compile those files and link it all together. So you might try to figure out whether a) that lib requires some config file (config.h or such) and whether you generate it using either predefined values or by using the PHP build system b) whether the lib requires special CFLAGS (run make VERBOSE=1 with a cmake build and look at the flags being used) once that information is gathered you can list the avro files in config.[m4|w32] and be done.In a few cases there might be things which need a patch, though. In general I'm no big fan of bundling libraries. that should only be done if it is complicated to get otherwise or changes the behavior too often. Linking against a library provided externally simplifies access to bug fixes in the lib itself. johannes
