 # Compiling iBMQ from source in Windows
 Compiling iBMQ from source is only recommended for experienced users.
 In addition to setting the "Path" System variable, one must also
-establish User variables "GSL_INC" and "GSL_LIB" leading to 
-GSL header and source files, respectively. 
+establish User variable "LIB_GSL" leading to GSL header and lib files. 
 
 In a sample installation:
-
-GSL_INC: C:/Program\ Files/GnuWin32/include
-GSL_LIB: C:/Program\ Files/GnuWin32/lib
+LIB_GSL: C:/gsl
 
 Note the use of forward slashes separating directories. The character
 "\ " handles spaces in directory names.
