[CMake] List all packages

[Lectem]

Hi,

Is there a way to list all the packages (both config files and find-modules) that find_package could find ?
Could we even imagine this would also permit to list the variables and targets created in it ?
I think that would be a very helpful to have for debugging find_package, especially when you don’t have access to the system having issues (user bug reports for example).


Cheers,
Lectem
