git-2.55.0 (for downloading some tests) and doctest
An Internet connection is needed for some tests of this package. The system certificate store may need to be set up with make-ca-1.16.1 before testing this package.
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.
