title: CMake & CTest : make test doesn't build tests
body: <p>I'm trying CTest in CMake in order to automatically run some of my tests using <code>make test</code> target. The problem is CMake does not "understand" that the test I'm willing to run has to be built since it is part of the project.</p>
  
  <p>So I'm looking for a way to explicitly specify this dependency.</p>
