Hello,

In **Professional CMake 17th** , I read some stuff about [CMP0135](https://cmake.org/cmake/help/latest/policy/CMP0135.html). The book and the documentation talk only about `ExternalProject_Add()`, but not about `FetchContent`.

And then I found the following ticket :  
[https://gitlab.kitware.com/cmake/cmake/-/issues/23560](https://gitlab.kitware.com/cmake/cmake/-/issues/23560)  
and the followoing merge request :  
[https://gitlab.kitware.com/cmake/cmake/-/merge\_requests/7316/](https://gitlab.kitware.com/cmake/cmake/-/merge_requests/7316/)  
both made by @craig.scott

The merge request seems to be done, but as there is no mention of `FetchContent` in the two documentation sources mentionned above, I was wondering if CMP0135 was considered by `FetchContent` ?

Thanks.

Yes CMP0135 should apply to FetchContent as well. I’ll take a look at updating the CMP0135 docs to make that clear when I get a chance.
