After working that way for years, by coincidence I just changed
testing for Open Watcom to use another approach that will be
easier to generalize for other compilers.

Now after building CMake with another compiler, open a terminal
with the environment configured for Open Watcom and do:

 >mkdir CMake-ow-build
 >cd CMake-ow-build
 >cmake ../CMake -G "Watcom WMake" -DCMake_TEST_EXTERNAL_CMAKE=...

where the "..." value is a path to the directory containing the
cmake, ctest, and cpack executables to be tested, such as:

 c:/path/to/CMake-other-build/bin

Then run

 >wmake

in case there are any test-only binaries to build.  Finally run

 >ctest

to launch the tests.  The ctest -j/-R/-V/etc. options will still work.
