| Summary | 0006846: extra unneeded libraries are added | ||||||||
| Description | Let's say to have the following (simplified) CMakeLists.txt: | add_library(mylib SHARED libsources...) | target_link_libraries(mylib lib1 lib2) | | add_executable(myapp appsources...) | target_link_libraries(myapp mylib) Then, when linking myapp, "-llib1 -llib2" is added on the linking line. The point is, is lib1 and lib2 are _private_ dependancies for mylib, why should they be added for myapp as well? After all, if myapp would need to use symbols from any of those, it must explicitely link to them (thus the developer must manually add the dependancy). Tested with CMake 2.4.8, and the "Unix Makefiles" generator (default on unix). | ||||||||

Your rationale fails for static linking. |

Where do you see "static linking" in the cmake snippet above? Supposing that represents a real example, why should cmake even think about "static linking" when I'm explicitely requesting the creation of *dynamic* library? |

This is expected behavior, but in cmake 2.6 there is now a way to change it with this target property: http://www.cmake.org/HTML/cmake-2.6.html#command_LINK_INTERFACE_LIBRARIES [^] |
