Well, I did a cursory test ages ago just to get a handle on what had CMakeLists.txt and what didn't. If we could identify solid criteria like you suggested "directories with both CMakeLists and Makefile.am" files, then it would be a simple process of walking the git tree with 'find' and identifying apps which met the checks and those that partially met and those that were just autofoo.
One issue I see is the use of .in.in and .in instead of .am, so we may need a fairly broad search of the variants of Makefile.am, configure.blah to get a valid picture of the state of the build setup.
I'll look for some tests, if you can think of others, let us know.
Everybody else as well.
Here is a preliminary list of modules converted to cmake that contain directories with a Makefile.am but no corresponding CMakeLists.txt. The list offers no conclusions. Just a list. Which items are legitimate remains to be investigated.
