<div>The problem was that I expected after running cmake with -DCMAKE_BUILD_TYPE=Release to have the project files generated only for a Release build type. It turns out CMake does not do that. After your suggestion, I found this entertaining discussion of this behavior:</div>

Ah yes, I remember. Using the release built clang libraries the headers<br>
end up doing different things because _DEBUG is defined in your<br>
project and not defined when the libraries were compiled.<br>
<br>
So this is another wrinkle that is specific to clang and not the CRT.</blockquote><div><br></div></div><div>Some feedback on Debug vs. non-Debug build.</div><div><br></div><div>I tried a build setup that I haven't seen documented anywhere on Clang's website (or on The Internet): </div>
