Thanks Greg, and Neo---although your input is more than I expected.
I found the topic deviated from the original point I was asking, because there are many aspects hidden behind my question that I do not know. However, It is easier for me to learn by example, especially on coding.
Normally, I found there is one layer missing to me when others library is installed in the system. Simply sudo apt-get install / sudo yum install etc does not help me in actual C coding from scratch.

Here, I want to stick to the tech and only the tech part, i.e: "In my this example, what is the correct/standard way to make use the downloaded htslib not installed system-wide? "

1) I want to confirm the options of my command line that are correct in general, while I'm trying to find the official reference (which normally do not have real hands-on example, e.g $ORIGIN);

2) Trying to catch the standard way to use non-system *.a and *.so files in C coding on top of point 1). Here "standard way" can be replaced with "common way" if there is not all-for-one solution, which is normally the case.
Two examples, (1) the standard way to use shared objects (.so) is to install them in the system directories Thanks Greg! This cleared my confusion. The not-answered part is how to make use of the *.so file when it is not installed system wide. (2) I saw people usually use static library for *.a files and dynamic library for *.so files, but Greg consistently use archives for *.a files and shared objects for *.so ones. It seems to me that they are different names for the same thing, but I might be wrong.
This was a so big confusing wording! And I owe an apology to all who read this post!
3) My point is what the right way(s)---may not be the best way--- is to use them.
Can I ask in another way:
What is the best practice to use others library (static *.a and shared *.so) not installed system-wide in C programming? I may need to start a new thread before the topic is veered too far off.

Thank you so much for your time!
