<p class="MsoPlainText">Thanks, but that’s approximately exactly what I’m trying to avoid doing. I cheat a little, in that I have a macro that will prepend a prefix to every element of a list. My motivation is avoiding situations where I add the prefix to
the files but forget to add the prefix when I call target_include_directories or suchlike.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I’m not sure anything trickier is workable in the CMake model, however. For example, hacking CMAKE_CURRENT_SOURCE_DIR might make sense for file paths, but if I then call add_subdirectory should it be rooted at the CMakeList directory
or the source root directory.<o:p></o:p></p>
