Summary:                    Change of CMakeLists.txt doesn't trigger reconfigure
Description: 
`cmake --build` command doesn't trigger reconfiguration of the project on OS X
when CMakeLists.txt changed.

Example:

add_executable(foo foo.cpp) # file foo.cpp exists

cmake -H. -B_builds
cmake --build _builds
# OK

change:
add_executable(foo foo.cpp boo.cpp) # file boo.cpp not exists
cmake --build _builds
# expected error, but no error reported

Ready-to-run example can be found:

Log from OS X machine:
* https://travis-ci.org/forexample/cmake-osx-no-reconfigure-bug/builds/83701171

Log for similar test on Linux machine:
* https://travis-ci.org/forexample/cmake-osx-no-reconfigure-bug/builds/83702953

CMake on Linux machine run reconfigure command and report an error:
  cmake -H. -B_builds --check-build-system CMakeFiles/Makefile.cmake 0
  -- Configuring done
  CMake Error at CMakeLists.txt:4 (add_executable):
    Cannot find source file:
      boo.cpp

same error expected on OS X machine
