Try to make the effective way to produce dynamic generated source files

[pustotnik]

ZenMake has ability to use a build task that generates source files for some other task(s). But if names of these files are unknown then only the 'group-dependent-tasks' parameter can be used to solve the problem when ZenMake cannot find such files. This parameter can slow building down and it looks like hack/workaround, not a normal solution. I'm not sure that it can be solved in more appropriate way with python/Waf limits but a solution maybe exists.

See "wafbook: 11.4.2. A compiler producing source files with names unknown in advance" for thoughts.
