Jiri Daněk created PROTON-2774: ---------------------------------- Summary: Support composite CMake builds Key: PROTON-2774 URL: https://issues.apache.org/jira/browse/PROTON-2774 Project: Qpid Proton Issue Type: Improvement Components: build, proton-c Affects Versions: proton-c-0.39.0 Reporter: Jiri Daněk Assignee: Jiri Daněk Fix For: proton-c-0.40.0
CMake recognizes the notion that project may be either top-level, or included from other projects that intend to depend on it. https://cmake.org/cmake/help/latest/variable/PROJECT_IS_TOP_LEVEL.html This inclusion is performed either with add_subdirectory() or by FetchContent_MakeAvailable(). There are several preconditions for this to work #. proton must compile cleanly with whatever compile (warning) flags the top-level project sets; I intend to clean proton so that it compiles with qpid-dispatch/skupper-router flags #. CMakeLists.txt need to be written to not assume that CMAKE_SOURCE_DIRECTORY corresponds to the currently active project. Use the PROJECT_SOURCE_DIRECTORY and similar variables instead. #. targets in CMakeLists.txt must be written so that they can be immediately used by the including projects #. tests and other miscellaneous parts of the project should not be enabled when proton is not the top-project As an example, the Google Test project supports this kind of composite builds. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
