The tests are run by ctest which does not expand VS vars like OutDir. 
Try this:

ADD_TEST( T1010 appproptest 
--Config=\${CTEST_CONFIGURATION_TYPE}/apppropteston.cfg )

Note the backslash.  This should put "${CTEST_CONFIGURATION_TYPE}" 
literally into the test file.  CTest will expand this with the current 
configuration (-C option) when running tests.

CMAKE_BUILD_TYPE is for the Makefile generators, so it is irrelevant 
here.  The -C option was originally meant for running tests but not 
building.  I see no reason that it should not work for driving build 
too.  Please submit a feature request:
