cmake does not run ctest.  ctest is driving the dashboard client build.
First it configures the project.  Then it builds the project.  Then it
runs the tests.  The "build the project" step means it needs to run the
native build tool.  ctest uses "cmake --build . --config Debug" to do
that.  The native build tool somehow exits non-zero, and "cmake --build"
returns that error code.  As far as "ctest" knows, "cmake --build ..."
is the build tool, and it exited with non-zero.  That is why the message
appears.
