Compile the source files. To change the install directory you must set cmake environment variable `${CMAKE_INSTALL_PREFIX}` (e.g. using command `ccmake ..` before calling `cmake ..`).
Its default value on UNIX-like/Linux systems is "/usr/local".
```sh
```sh
cmake ..
cmake .
make
make-j4
```
```
Finally, you can install the library (`sudo` is required only if `${CMAKE_INSTALL_PREFIX}` is a system diretory managed by administrator user root).
