Summary0014031: export() segfault when target list contains undefined target
DescriptionWhen using the export() command to export targets for use in another CMake project, if the list of targets passed-in contains a target that does not exists, then an error message should be displayed.

Instead of an error message, CMake 2.8.10.2 on OSX crashes with a segfault.
Steps To ReproduceCreate a CMakeLists.txt file with 1 or more add_executable() or add_library() statements.
Add the targets made by the add_executable and/or add_library() to a list.
Add an export() command that is passed the list of target names and generates a something.cmake file.

Running "cmake" on this file should work as expected at this point.

Modify the list such that it also contains an "extra" target in it that doesn't really exist.

Running "cmake" on this file will cause a segfault.

 Does this still occur with a recent nightly build?

Several significant changes have been made to the relevant code since 2.8.10.2.
