Support FPM

Hey!
I'm currently searching for a fast sparse linear algebra lib to use in my project and came across this project. Since setting up the project is always such a hassle I'm quite fond of the Fortran Package Manager:
https://fpm.fortran-lang.org/

Would it be possible, that you could add a fpm manifest to this project? As far as I understand it, this would be sufficient so that fpm can pick this up and add it as dependency to any fpm project.

I have no idea, if this is feasable with your project, but I hope you have time to look into it.
