KUDU-2427: only add -fno-sized-deallocation for C++ files
Ubuntu 18.04 has a gcc that's new enough to support -fsized-deallocation.
But, if -fno-sized-deallocation is added to a C file's compilation flags,
the compiler will emit a warning:
cc1: warning: command line option ‘-fno-sized-deallocation’ is valid for
C++/ObjC++ but not for C
The problem is that we want to apply this flag only to "exported" targets,
but we have one such target (gutil_exported) that has both C and C++ files
in it. To address this, we can use a cmake generator expression[1] to
conditionally add the flag only to the C++ files in the target. This means
adding the flag with target_compile_options(), as set_target_properties()
does not support generator expressions.
