##Configuration & Dependencies
### Integration with CMake
If you are using CMake and want to use its configuration abilities to save
you the trouble, you can easily integrate Backward:
```
add_subdirectory(/path/to/backward-cpp)
# This will add backward.cpp to your target
add_executable(myproject mysource.cpp ${backward_ENABLE})
# This will add libraries, definitions and include directories needed by backward
add_backward(myproject)
```
### Compile with debug info
You need to compile your project with generation of debug symbols enabled,
