Use of variable $ORIGIN & -rpath

If you link to a shared library intead of the archive it's a little more complicated.
Thank you for point that out. Actually I meant the archive here.
I happened to found this article using a special variable $ORIGIN, and that seems to make everything working now.

Code:
$ LIBROOT="/home/yifangt/Study/C/VCF/htslib-1.10.2" 
$ gcc -Wall -O3 -o vcf_parser01 vcf_parser01.c vcf.c  -I ${LIBROOT}/htslib -I ${LIBROOT} -L ${LIBROOT} -Wl,-rpath,"\$ORIGIN"  -lhts
$ ./vcf_parser02 
Usage: print-ctg <in.vcf>

But, I could not find the reference in the GCC manual about this variable, or the -rpath. I am not sure if this is the correct way to do the job.
Especially, what's the standard way?
Thank you very much again.
