The build fails because it is using a cmake feature that was introduced in cmake 3.18 and you 
are using cmake 3.16. As gnucash claims to be buildable with cmake as old as 3.14, this is 
actually a bug in our build system, not cmake nor your system.

I have pushed a fix that will be included in upcoming gnucash 4.9. Meanwhile you can apply 
the fix manually in your source code if you want to continue your experiment. Below is the 
applied patch:
