Hi all,
I'm trying to use a new feature of releases 2.8.4/5, that is the
possibility to define dependencies for IMPORTED targets and when I run
cmake I get a SIGSEV signal. Trying to get some more info with Valgrind
I found that:

So it looks like cmake is trying to access (dereference) a NULL pointer.
In particular, digging in the source code, the issue arises (apparently)
in cmComputeTargetDepends.cxx(AddTargetDepend) at line 279
cmTarget* transitive_dependee =
dependee->GetMakefile()->FindTargetToUse(i->c_str());
when cmake recursively calculates the dependency of my target, which
relies on all IMPORTED targets, and hits an IMPORTED target (a library)
with NO dependencies, that is the last leaf of my deps tree. The
"transitive_dependee" returned by FindTargetToTuse turns out to be a
NULL pointer and when IsImported() is called on it, it makes the program
crash.
Have anyone else tried to use this feature of cmake 2.8.4 and eventually
discovered this issue?
Cheers,
Marco
