Hi,

The upstream docs for building from source say:

"You need a C++ compiler with C++17"

but offer no further guidance.
I went for the minimum change rather than risk breaking things on
systems I can't test.
If it was just for Debian then I totally agree your solution is the
cleanest.

Cheers,
Scott
