-----------------------------------

             Summary: Subordinate CMakeLists.txt files should not build on their own
                 Key: PROTON-248
                 URL: https://issues.apache.org/jira/browse/PROTON-248
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c, proton-j
    Affects Versions: 0.4
         Environment: Windows, perhaps all.
            Reporter: Cliff Jansen
            Assignee: Cliff Jansen


If CMake is pointed to the wrong (subordinate, instead of top level) directory, the CMakeLists.txt file should detect the problem and exit with a clear error message instead of generating a bogus build accompanied by a vague warning.

To reproduce:

cd trunk\proton-c
mkdir build
cd build
cmake [args] ..
[build away]

In which case cmake uses trunk/proton-c/CMakeLists.txt as the top level instead of trunk/CMakeLists.txt.
