Debug also adds padding between functions and stack checking which can
significantly add to code size for smaller libraries... or libraries with
lots of tiny functions.

I am not entirely sure what you mean but CMake's default flags for the Visual \
Studio compiler when building "Debug" or "RelWithDebInfo" use /Zi \
(debug information in external pdb) rather than /Z7 (embedded debug information; no \
pdb is generated).<br> <br>
Maybe your project replaces the default \
flags?</blockquote><div><br></div></span><div>No Z7 or Zi anywhere in the CMake files \
