Thanks for the tip. The outcome, however, is not at all what I expected. Check
this out (sorry that the line wrapping will make the shell command look
weird):

It works! It works! Now I don't have to debug anything, since it suddenly
works. So, let's turn off the debugging:

It's perfectly reproducible: I can repeat either way many times, and it works
only with debug-trycompile on.
I examined the CMakeError.log. It's my first time looking at it, so I don't
really know what I expect to see, but it doesn't seem to be weird: it looks
like it tried to compile a file and encountered an undefined symbol. I just
don't know why. I'm attaching both the error & output logs, just in case your
far more experienced eyes catch anything.
I can try to reduce to a more minimal test case and send the required files to
the list if that would be useful.
Best,
