	Hi,
it matches what I see here. The CMake (3.17.3 here) keeps the escaped
characters, thus it makes `\"` from the `\\\"` in the CMakeLists.txt
file. See my initial email, it shows what the variable expands to in
the source code. You can use also gdb to check it out in runtime.

As I wrote earlier, I do not know whether it's a changed behavior in
the (newer) CMake or if it was like that from the very beginning.
	Bye,
	Milan
