For example, consider the link "libraries" // /usr/lib/libtiff.so -ltiff // Is this one library or two? The solution implemented here is the // simplest (and probably the only practical) one: two libraries are // the same if their "link strings" are identical. Thus, the two // libraries above are considered distinct. This also means that for // dependency analysis to be effective, the CMake user must specify // libraries build by his project without using any linker flags or // file extensions. That is, // LINK_LIBRARIES( One Two ) // instead of // LINK_LIBRARIES( -lOne ${binarypath}/libTwo.a ) // The former is probably what most users would do, but it never // hurts to document the assumptions. :-) Therefore, in the analysis // code, the "canonical name" of a library is simply its name as // given to a LINK_LIBRARIES command. // // Also, we will leave the original link line intact; we will just add any // dependencies that were missing. // // There is a problem with recursive external libraries // (i.e. libraries with no dependency information that are // recursively dependent). We must make sure that the we emit one of // the libraries twice to satisfy the recursion, but we shouldn't // emit it more times than necessary. In particular, we must make // sure that handling this improbable case doesn't cost us when // dealing with the common case of non-recursive libraries. The // solution is to assume that the recursion is satisfied at one node // of the dependency tree. To illustrate, assume libA and libB are // extrenal and mutually dependent. Suppose libX depends on // libA, and libY on libA and libX. Then // TARGET_LINK_LIBRARIES( Y X A B A ) // TARGET_LINK_LIBRARIES( X A B A ) // TARGET_LINK_LIBRARIES( Exec Y ) // would result in "-lY -lX -lA -lB -lA". This is the correct way to // specify the dependencies, since the mutual dependency of A and B // is resolved *every time libA is specified*. // // Something like // TARGET_LINK_LIBRARIES( Y X A B A ) // TARGET_LINK_LIBRARIES( X A B ) // TARGET_LINK_LIBRARIES( Exec Y ) // would result in "-lY -lX -lA -lB", and the mutual dependency // information is lost. This is because in some case (Y), the mutual // dependency of A and B is listed, while in another other case (X), // it is not. Depending on which line actually emits A, the mutual // dependency may or may not be on the final link line. We can't // handle this pathalogical case cleanly without emitting extra // libraries for the normal cases. Besides, the dependency // information for X is wrong anyway: if we build an executable // depending on X alone, we would not have the mutual dependency on // A and B resolved. // // IMPROVEMENTS: // -- The current algorithm will not always pick the "optimal" link line // when recursive dependencies are present. It will instead break the // cycles at an aribtrary point. The majority of projects won't have // cyclic dependencies, so this is probably not a big deal.
