Summary:                    CMake crashes when reconfiguring build
Description: 
Attached is a reduced test case that reliably crashes CMake.

Steps to Reproduce: 
1. Execute the following commands:
~~~~~
mkdir build && cd build
cmake ../path/to/source/folder -DCMAKE_C_COMPILER=cc -DFOOBAR=0
~~~~~
CMake should abort the configure with the message: "CMake Error at
CMakeLists.txt:8 (message):  FOOBAR was not set"

2. Execute the following command:
cmake ../path/to/source/folder -DCMAKE_C_COMPILER=cc -DFOOBAR=1

Expected behaviour:
CMake reconfigures the project.

Actual behaviour:
CMake displays the following message, then crashes:
~~~~~~
-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= cc

CMake Error at CMakeLists.txt:3 (add_library):
  add_library cannot create imported target "testlib" because another target
  with the same name already exists.

[1]    20462 segmentation fault (core dumped)  cmake ../ -DCMAKE_C_COMPILER=cc
-DFOOBAR=1

Additional Information: 
Core dump is included in the attachment.
