libgmm-dev binary package in Ubuntu Oracular arm64

 GMM is a framework of pre-defined methods for matrix computation. It is built
 as a set of generic algorithms for any interfaced vector type or matrix type.
 .
 It can be viewed as a glue library allowing cooperation between several vector
 and matrix types. However, basic sparse, dense and skyline matrix/vector types
 are built-in, hence it can be used as a standalone linear algebra library.
