# This file comes from: https://github.com/conan-io/cmake-conan. Please refer
# to this repository for issues and documentation.

# Its purpose is to wrap and launch Conan C/C++ Package Manager when cmake is called.
# It will take CMake current settings (os, compiler, compiler version, architecture)
# and translate them to conan settings for installing and retrieving dependencies.

# It is intended to facilitate developers building projects that have conan dependencies,
# but it is only necessary on the end-user side. It is not necessary to create conan
# packages, in fact it shouldn't be use for that. Check the project documentation.

# version: 0.16.0-dev
