[CMake] COMPILE_FLAGS suggestion

[Brandon J. Van Every]

SET_TARGET_PROPERTIES(file PROPERTIES COMPILE_FLAGS
  "-DBLAH -DBLLAH -DBLLAAHH")

is a very common form that will be used heavily by people in CMake 2.3 
onwards.  Anybody who has to do lotsa trivial combos of libraries will 
be doing it; for instance, shared vs. static libraries, and debug vs. 
release libraries.  The quotes around the flags are necessary because 
items in a PROPERTIES list have to come in pairs.  I humbly submit that 
the following syntax would be of great use to people:

SET_COMPILE_FLAGS(file -DBLAH -DBLLAH -DBLLAAHH)

so that they don't have to be "quote paranoid" about everything, and 
also have less to type.  I would have created a macro for this, but my 5 
minute perusal of the docs did not yield a painless way to manipulate 
ARGV.  On the positive side, at least I finally understood at an 
intuitive level what Scheme's CAR and CDR are for.  (It's so you can 
knock the front off the arguments.)
