Since this issue has come up in several posts (the chicken problem, and the qt header file problem), I thought I would try to explain how generated files work in CMake 2.4.
In CMake 2.4, you should not have to specify OBJECT_DEPENDS, or even set PROPERTIES GENERATED true. You should just make sure that the chain of inputs to outputs is complete. Inputs are specified with DEPENDS or MAIN_DEPENDENCY, and outputs are specified with OUTPUT. custom_command1 DEPENDS foo OUTPUT bar custom_command2 DEPENDS bar OUTPUT car custom_command3 DEPENDS car OUTPUT done.c add_library(thing done.c) (foo is a file on the disk, bar is created from foo, car is created from bar, done.c is created from car) cmake will make sure the commands are run 1,2,3 so that done.c can be created for use by the library thing. A configured file is really not a generated file, as it will be around by the time cmake is run since the cmake run creates it. The GENERATED status is used to tell cmake about files that will not be created until the build process is run. Outputs of custom commands are automatically marked generated. OBJECT_DEPENDS was added for support of generated .h files. However, in CMake 2.4 its use is deprecated and all you need to do is put the .h file in the list of sources. In addition, you have to make sure that the directory where the .h file will be is in the -I paths for the build. INCLUDE_DIRECTORIES should be used for that. In summary OBJECT_DEPENDS and GENERATED should not be required in new projects based on CMake 2.4. -Bill _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
