Still can't include 3rdparty library after an hour of various tutorials [message #1766600]

I'm trying as hard as I can to not insult the program here, so work with me

I'm sure you get this a lot, but am I just an idiot or something? I seriously don't understand what I'm doing wrong that is causing this issue

[inserting links later]

all I wanted to do was see if I could try out a library, but apparently I'm too stupid to add them in the first place, I have no idea what I'm doing wrong, because I've followed several tutorials and all of them seemed to say the same thing, add the path to Includes and Libraries, and add the name to -l, but I'm STILL getting the "Cannot find -I[library path]" after trying tens of variations

what. am. i. doing. wrong.

If you think the parameter following -l (small L) is a path then you don't understand what the option means.
See ftp://ftp.gnu.org/old-gnu/Manuals/ld-2.9.1/html_node/ld_3.html

Eclipse is an editor with capabilities to call external tools to perform a build.
It primarily expects to use GNU Make to actually execute the tools.
https://www.gnu.org/software/make/manual/

You need to understand how to build an executable using the compiler and linker then executing them via Make.
Once you understand that, then what Eclipse is doing is fairly obvious.
Explaining how the external tools work and what they expect is beyond the scope of this forum.

I suggest you look for tutorials on how to compile an link an executable from the command line and using Make.
Eclipse pretty much expects you to have this understanding.
There are a number of excellent tutorials available but only you know how much detail you need.

If you are using GCC to compile and link then you could try these
https://gcc.gnu.org/onlinedocs/
https://gcc.gnu.org/onlinedocs/gcc/
