Hi, I just installed a new Ubuntu 22.04 LTS system and tried to build UHD from source. I successfully built UHD and installed (to a different install prefix in my home folder, ~/uhd/UHD-4.2/). But, when I tried to build my own OOT stuff, I got lots of cmake errors related to INCLUDE dirs NOTFOUND. Then, I tried to build the un-modified Etttus rfnoc-example by adding a build folder (in-tree) and running cmake. I encountered the same errors. Any ideas? Rob
