For some reason this didn't work with my actual cmake environment, but I could enable it on a simple test environment. I can look into that later. Here my concern is that you cannot use unity builds if you need compile_commands.json (-DCMAKE_EXPORT_COMPILE_COMMANDS=ON); for example if this is required by your IDE or other build tools. When unity builds are enabled the json file is not usable since it contains only commands for the unity source files and doesn't describe the original source files. Is there an intent to address this before the 3.16 release? Or is this a known limitation, which may or may not be addressed in some future version of CMake? If the latter it should probably be added to the release notes and/or documentation for unity builds.
