R package gsl problems when downloading in Rstudio

Question

I need to download a package that apparently needs gsl installed beforehand. I am using Rstudio with R version 3.6 on Windows. When I try to install it using install.packages() I get this message:

Installing package into ‘(my library)’ (as ‘lib’ is unspecified) installing source package 'gsl' ... package 'gsl' successfully unpacked and MD5 sums checked using staged installation

WARNING: this package has a configure script It probably needs manual configuration

I found this thread with the same error message but I tried doing the same procedure as @tchevrier and the same result keeps coming up.
