Even after my change this one is still failing.

Someone with access to the box would have to
cd ${CMAKE_BUILD_DIR}/Tests/Module/GenerateExportHeader/libsharedtest/fail1
rm -rf *
cmake ../test1

then inspect the trivial ../test1/CMakeLists.txt to see why it is failing.

I made another guess and pushed another patch, but it's a quite 
inefficient way to fix this issue. Does anyone have access to that box?

Yes. CDash seems to fail if there is no executable of the correct name 
which runs successfully.

For Watcom I create a trivial executable with the appropriate name 
before I return(). For not watcom the tests are run and the trivial 
executable is not created. I think it's correct as-is. The machine 
hasn't yet finished to confirm that though.
