get stuck on Fetching LibIAMF

Linux LMDE6 (Debian Bookworm)
cmake 3.31

It gets stuck at this point - Fetching LibIAMF

```
-- Fetching LibIAMF
CMake Warning (dev) at /usr/share/cmake-3.31/Modules/FetchContent.cmake:1953 (message):
Calling FetchContent_Populate(libiamf) is deprecated, call
FetchContent_MakeAvailable(libiamf) instead. Policy CMP0169 can be set to
OLD to allow FetchContent_Populate(libiamf) to be called directly for now,
but the ability to call it with declared details will be removed completely
in a future version.
Call Stack (most recent call first):
third_party/libiamf/CMakeLists.txt:33 (FetchContent_Populate)
This warning is for project developers. Use -Wno-dev to suppress it.
```

setting CMP0169 to OLD does not help
