{
// There are two key parts of the dependency analysis: (1)
// determining the libraries in the link line, and (2) constructing
// the dependency graph for those libraries.
//
// The latter is done using the cache entries that record the
// dependencies of each library.
//
// The former is a more thorny issue, since it is not clear how to
// determine if two libraries listed on the link line refer to the a
// single library or not. 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. Note that
// the link line is always correct, just not necessary optimal.
