<p class="MsoNormal">I think if you manipulate the target property <a href="https://cmake.org/cmake/help/latest/prop_tgt/INCLUDE_DIRECTORIES.html" target="_blank">
INCLUDE_DIRECTORIES</a> directly, you should be able to force a "." in there without having it substituted for an absolute path. By this I mean use set_property() or set_target_properties() rather than target_include_directories() or include_directories().
Note, however, that the documentation for the INCLUDE_DIRECTORIES property explicitly recommends against adding relative paths to the property like this (but in your case it sounds like you really want a relative path, so maybe this is a valid exception to
that advice).<o:p></o:p></p>
