[R-pkg-devel] Link to MKL instead of RBLAS on CRAN

Hi,

Is it possible to link with MKL instead of RBLAS when submitting my package to CRAN?

Usually, it's not the business of a package to choose a BLAS to link to. 
Many options exists for this on the user's side. For example, at 
installation of R you can see 
https://cran.r-project.org/doc/manuals/r-release/R-admin.html#BLAS or 
https://www.intel.com/content/www/us/en/developer/articles/technical/using-onemkl-with-r.html
Another option for "standard" R which can work, is simply to simlink 
Rblas.so to libopenblas.os or whatever BLAS you want. For MKL it can be 
a little trickier as it requires some additional libraries. It is up to 
you to make them findable at run time.

Best,
Serguei.

Do CRAN support other BLAS libraries?

Best,
