Wow the property idea is perfect. I will use that instead. I tend to think too much in terms of either "variable" or "cache variable", I tend to forget about properties.<div><br></div><div>Thanks!<br clear="all">

</div></div>AFAIK if the cache variable is INTERNAL, you don't need FORCE.<br>
list(APPEND) can't do this for you, but you can use a un-cached variable<br>
to assemble the list in the loop, and the set the INTERNAL cache<br>
variable after the loop finished.<br>
<br>
Also, if the values in that variable are not supposed to be persistent<br>
across multiple CMake runs, you might want to use a global property instead.<br>
