Clone this repository

Clone with submodules and pass the --recursive-submodules flag:

$ git clone https://github.com/taketwo/pcl-mean-and-covariance.git --recursive-submodules

Configure with CMake

$ cd <path to>/pcl-mean-and-covariance/
$ mkdir build
$ cd build/
$ cmake ..

Note: CMake 3.5 or higher is required.

Install datamash

This is required to build and run the benchmark. On later versions of Ubuntu, this can be installed as a prebuilt package with the following command:
```
$ sudo apt install datamash
```
However on older systems it may be necessary to install datamash from source. See the datamash download page for details.
Build and run benchmarks

From the build folder, run:
```
$ make benchmarks
```
Build and run tests

From the build folder, run:
```
$ make tests
```

If, when running make benchmarks you get the following error:

Console.cpp:27:20: fatal error: curses.h: No such file or directory
  #include <curses.h>

This is because the ncurses module is not installed on your system. You can install it with the command:

$ sudo apt-get install libncurses5-dev
