Ensure your CMake version is >= 3.16 with `cmake --version`. If your system doesn't provide a suitable version of CMake, you can download a binary release from the [CMake website](https://cmake.org/download).
Ensure your gcc version is >= 10 with `gcc --version`. Otherwise, install it.
On Ubuntu it's in the repositories of 20.04 (Focal) and later - add the `ubuntu-toolchain-r/test` PPA if you're running an older version:
```bash
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
```
On Debian you can use the Debian testing branch:
```bash
sudo echo "deb http://http.us.debian.org/debian/ testing non-free contrib main" >> /etc/apt/sources.list
sudo apt update
```
Now on Ubuntu or Debian you can install gcc-10 with apt like this:
```bash
sudo apt install gcc-10 g++-10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 900 --slave /usr/bin/g++ g++ /usr/bin/g++-10
```
If you don't want to stay on the Debian testing branch you can switch back by running:
```bash
sudo sed -i '$d' /etc/apt/sources.list
sudo apt update
```
Make sure you have all the dependencies installed (`ninja` is optional, but is faster in practice): Make sure you have all the dependencies installed (`ninja` is optional, but is faster in practice):
