Hello every one.
Recently, I try to rewrite a large project's building system by using cmake. I meet a difficult point, how to detect & set dependences when build-time. I have lot of this requirement, and currently I solve it with some terrible ways. I want some refined ways. For example: Using precompiled header file. Cmake do not support pch directly and can not detect a header's dependences as a source file. I can't set pch's dependences when cmake-time because it's changed frequently and it's dependences is tree structures. Currently, I create a assistant library-target, it have a cpp file only that includes precompiled header, and then add_custom_command depend it. So, once assistant library-target build, the precompiled header is recompiled. (How terrible it is.) Compile qrc file. If I scan qrc's dependences on cmake-time, and I remove some of file from qrc file after running cmake.Then I got an error, because qrc still depend it. So, currently I use "configure" command to copy qrc file in order to update qrc's dependences when cmake to check-build-system. Compile idl file. Just as previous requirement, idl's dependences is tree structures. In addition I write a script to scan dependences. How can I run this script on build-time. Currently, I have no ways. In CMake 2.8's document I see that add_custom_command has an IMPLICIT_DEPENDS but I can't find any more data about it. And I have not found any where use it. -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
