This is a master conanfile.py which can be symlinked into a root directory and automatically discover conanfile.txt
|
||
|
|
from child packages from nerdcruft. (ie, from the glob cruft/*/conanfile.txt).
|
||
|
|
|
||
|
|
It also looks for a file _conanfile.txt in the same directory as this script. This config is loaded at the end and so
|
||
|
|
its [options] section will override any other options present in the defaults, or child packages.,
