## Getting started
### Get the code
```bash
git clone https://github.com/fortran-lang/fftpack.git
cd fftpack
```

### Build with [fortran-lang/fpm](https://github.com/fortran-lang/fpm)
Fortran Package Manager (fpm) is a package manager and build system for Fortran.   
You can build using provided `fpm.toml`:
```bash
fpm build
fpm test --list
fpm test <test_name, see `fpm.toml` or list>
```
To use `fftpack` within your `fpm` project, add the following to your `fpm.toml` file:
```toml
[dependencies]
fftpack = { git="https://github.com/fortran-lang/fftpack.git" }
```

## Build with Make
Alternatively, you can build using provided `Makefile`:
```bash
make
```

## Build with CMake
This library can also be built using CMake.  For instructions see [Running CMake](https://cmake.org/runningcmake/).  CMake version 3.24 or higher is required.
