Summary:                    Optionally disable build order dependency
target_link_libraries
Description: 
target_link_libraries adds transitive link dependencies and build order
dependencies between the target and its dependencies. In many (if not most)
cases the build order dependency is not necessary and results in an overlay
constrained dependency graph, which limits parallel execution of the build.

Short of discarding transitive link dependencies and maintain all dependencies
in each final target, I haven't found a CMake script workaround for this
problem.

I tried soliciting some feedback over the CMake mailing list earlier this year,
without any response: http://www.cmake.org/pipermail/cmake/2012-July/051351.html

I found  modifying the source to not add these build order dependencies for
static libraries was easy enough, and I was hoping there would be some interest
in finding some way of adopting this feature into the product.
