allow injection of additional CFLAGS

[umlaeute]

it seems that the CMakeFile sets the build flags

o2/CMakeLists.txt

Line 361 in 151b1c6

set(CMAKE_C_FLAGS "-std=c11 -mcx16")

in a way, that does not allow the user to inject additional build flags.

would it be possible to use something like this instead:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -std=c11 -mcx16")

?

Yes, I made the change. As far as I can tell, with the change, you can set CMAKE_C_FLAGS in the cache to "extra" flags and get "-std=c11 -mcx16" added automatically.

As far as I can tell, [..]

yes, this was my intention.

Yes, I made the change

i don't see it in current master:

o2/CMakeLists.txt

Line 362 in e83488f

set(CMAKE_C_FLAGS "-std=c11 -mcx16")

am i missing something?
