Provide RcppGSL Compiler and Linker Flags
CFlags return the required flags and
options for the compiler and system linker in order to build against
GNU GSL. This allows portable use of RcppGSL (which needs the
GNU GSL) as package location as well as operating-system specific
details are abstracted away behind the interface of this function.
CFlags are commonly called from the files

A boolean determining whether the requested value is returned on the standard output, or silenly as a value.
Thee functions are not meant to used interactively, and are intended solely for use by the build tools.
The values that are returned are acquired by the package at load
time. On Linux and OS X, the
pkg-config program is queried. On
Windows, environment variables used for GNU GSL builds with R are used.
A character vector suitable by use by the system compiler linker in order to compile and/or link against the GNU GSK.
