As I commented in the issue #195, this PR exposes all stacktrace libraries as boost features, mirroring what's available in the CMakeLists.txt in this project. So users will be able to build or not specific libraries present in this project. Here are some keypoints to evaluate these new changes:
- Added `build-stacktrace-feature` as generic rule validate on/off entry from users for each feature
- For `addr2line` I added a rule to disable in case using Windows and not Cygwin. It reflects the rule present in CMakeLists.txt: https://github.com/boostorg/stacktrace/blob/develop/CMakeLists.txt#L67close#195
