Conan profile files from current CMake config

Hi Denis,

No there is no current way to generate profiles, from CMake or even from conan command line. Those files have to be manually written. It is a relatively new feature, so creating profiles on the fly hasn't been a thing yet. It tend to be the opposite, we have had some questions regarding how to share profiles between teams, so creating the profiles in a repository and letting the --profile point to any specific user path was an implemented feature request.

The conan.conf and profiles are hiearchical (like git configuration). Profiles overwrite (or partially overwrite, if you define it as such) the contents of user conan.conf. Changing that to a default profile might change behavior and break for a few users.

Conanfile.txt and conaninfo.txt are quite different files. Conanfile.txt is an input file that can be committed to Version Control, serving for many users under different OS and compilers. Conaninfo.txt is the saved snapshot of a the configuration for a certain conan install invocation. This file shouldn't typically be committed to version control, but it is a good log, to be saved with the binary artifacts. So it contains, for example, the OS, the compiler, etc. That information cannot be stored in conanfile.txt, is not a limitation, it is by definition that it can be the same information.

Hi @traceon,

Besides the questions, I think that there is no specific action required, so I am closing this issue, but please comment or reopen if necessary. A feature request could be that of "conan generating profiles", but as I told you, most of the feedback about the feature actually points in the opposite direction. If you still interested, maybe submit it to the main conan repository to get the feedback of other users.
Thanks!
