[CMake] ctest meant to be re-entrant?

Thanks, that does help.  Could you tell me if the following 
approach constent with what you guys intended?

I want some parts of "CTestTestfile.cmake" to be automatically generated from the CMakeLists.txt files in my source directory tree.

OTOH, I also want to supply some additional information ctest.  For example, 'set(CTEST_BUILD_NAME "myBuildName")'.

So I do this:

1. Have a permanent (e.g., non-generated) file 
   "MyCTestScript.cmake" with the following content:

   INCLUDE("CTestTestfile.cmake")
   SET(CTEST_BUILD_NAME "myBuildName")

2. When I want to run tests, I use this command:
   ctest -s MyCTestScript.cmake -D Nightly
