------------------------- LIBGSL ERROR ---------------------------------
Configuration failed because environment variable LIB_GSL was not found.
Set variable LIB_GSL to the parent of the directory containing libgsl.a,
for instance ${RTOOLS43_HOME}/x86_64-w64-mingw32.static.posix. Note the
use of forward instead of backward slashes in the directory path. If GSL
(>= 2.2) is not yet installed, preferably install GSL using the Rtools
package manager, e.g. pacman -S mingw-w64-{i686,x86_64}-gsl. (See the
Rtools documentation for additional details).
