# Update packages
To update packages, run cmake with the additional option `-DCPM_RESET=ON`. To keep the project working offline after the update, set `-DCPM_RESET=OFF` afterwards.
# Installation
To add CPM to your current project, copy the scripts in the `cmake` directory into you current project project. The command below will perform this automatically.
```bash
wget -qO- https://github.com/TheLartians/CPM/releases/download/v0.2/cmake.zip | bsdtar -xvf-
wget -qO- https://github.com/TheLartians/CPM/releases/download/v0.3/cmake.zip | bsdtar -xvf-
```
