COMPILE_FLAGS
-------------

Additional flags to be added when compiling this source file.

These flags will be added to the list of compile flags when this
source file builds.  Use :prop_sf:`COMPILE_DEFINITIONS` to pass
additional preprocessor definitions.

Contents of ``COMPILE_FLAGS`` may use "generator expressions"
with the syntax ``$<...>``.  See the :manual:`cmake-generator-expressions(7)`
manual for available expressions.  However, :generator:`Xcode`
does not support per-config per-source settings, so expressions
that depend on the build configuration are not allowed with that
generator.
