[CMake] Running tests only on modified projects....

[David Cole]

It is presently not possible because there is no connection (other
than the full path to the executable and the arguments you pass to it)
between a test executed by ctest and the build products produced by
CMake and the native build system.

What is necessary is a way to connect a test and its inputs back to
the build products that lead into it such that it's part of the
build-time dependency analysis that takes place when an incremental
build is performed. It's very much a non-trivial set of tasks that
need to occur before this becomes possible in a reliable manner.


HTH,
David
