Thanks! This worked for my needs. Ninja said my command line changed. So
I used the generated compile_commands.json before and after a cmake run,
diff'ed those two files and was able to zero in on the issue. Thanks for
the tip. Worked great. Have to store that one away for future use.

Is there a way to determine which files in my build directory have
changed for a given run of CMake? The use case is that I made what I
thought was a small change to my configuration using cmake and when
I went to build it was basically a full recompile. During our cmake
run we do use configure_file(...) to generate headers and sources
some of which basically get included in every source file. I am
thinking that I have a dependency on generating those files when I
probably do not have to.
I use Ninja as my build system if that helps. I could always just
hack a local git repo for the build folder, commit everything, run
cmake and see what got changed. Anybody have a better idea?
Thanks
