Thanks for the help.<div>I'm sorry if my question was not clear enough or maybe I don't understand your answer</div><div><br><div>My question was how the parent directory may inherit the include directories from the child directory (added with add_subdirectory) ?</div>
<div><br></div><div> The current behavior is that the include directories from the child directory are added to the list of includes in the parent.</div></div></blockquote><div><br>Elizabeta,<br><br>Provided the directory name is an absolute path I think you could use the PARENT_SCOPE option to set() to pass the include directories up a directory to the parent. This is provided you're using CMake >= 2.6.0. If you are on 2.4.x or have to pass variables up many directories there are alternatives to this that will effectively provide you global variables (was a recent thread on the mailing list about this).<br>
