Can you please provide more description as to why this is necessary?

I realize that I overlooked the actual nature of this line: It does have an effect on the project commands in the subdirs, in particular for ls-qpack. Without that line, CMP0077 would might be unset after subdir project, regardless of the top-level choice.
(I tested this in a separate project now. CMake documentation didn't seem entirely clear.)

Nevertheless it might become obsolete in the future when the subprojects raise their minimum required version. And with modern versions of CMake, version lower than 3.10 are causing deprecation warnings.
