[CMake] set_property() scope qualifier question...

Drat.  Well...  guess this is a feature request then: being able to  
set properties on a per source and per target (or test).  :~]

My use of patch(1) does exactly that, let's me use -DTESTING_FOO and - 
DTESTING_BAR.  I find that to be less than ideal and thought that I  
was missing something or wasn't aware of a trick using if() or some  
other something.

Thanks in advance and thanks for cmake(1).  I'm very happy not using  
auto* anymore (though I wish there was a "create an sh(1) script mode  
for source distributions" when distributing source tar files).  -sc
