Hi List

I am trying to use g-expressions in nativ-search-paths field, but it 
fails with an error message, what is the issue her:

     (native-search-paths
      (list (search-path-specification
	    (variable "CFDEM_SRC_DIR")
	    (files #~'((string-append "share/" #$name "-" #$version))))))

and the error message:

Backtrace:
           11 (primitive-load "/gnu/store/3hbiwibrp9if0dhvyyhhdk87gb8…")

ERROR: In procedure string-append:
In procedure string-append: Wrong type (expecting string): quote

which looks like he is trying to append a string to a string which 
should work in my opinion?
