## Installation of Fast_float

Install fast_float by running the following commands:

    mkdir build &&
    cd    build &&

    cmake -D CMAKE_INSTALL_PREFIX=/usr \
          -D CMAKE_BUILD_TYPE=Release  \
          -G Ninja ..

Now, as the `root` user:

    ninja install

To test the results, issue: cmake .. -D FASTFLOAT_TEST=ON && ninja && ninja test. Note that the tests download some test files and the external doctest test framework from the Internet, and the doctest package would have been installed if the test suite had run before ninja install, so don't run the test suite before installation.
