Scipion build times distribution

---

As you can see in the chart, the packages that take most time to compile are cmake and opencv:

If you want to save precious compilation time, you can avoid both of them (provided you don’t need opencv functionality). cmake is needed for building some scipion modules, but the installer can use any cmake available in your system. So, if you don’t have cmake already installed, it will be faster to install the binary version with your package manager (for example, apt-get) than to compile it using scipion install cmake
