head of line cannot run sample application

[pjorourke05]

I am using Qt 5.15.0. I followed the steps in the readme for building the library and sample code from scratch. everything seems to build fine but when I run the sample application I get the follow.
error while loading shared libraries: libQt5JsonSerializer.so.4: cannot open shared object file: No such file or directory
Now i double checked the make files for sample which pointed to the correct path for the library. So I don't know what the issue could be. Any help would be much appreciated. attached is my console ouput for two commands. Also should my bin folder include anything? cause at the moment its empty
makeall_output.txt
makeinstall_output.txt

if you are available. I am having several issues try to use the library. I have tried installing using the repo through the maintenance tool or even building in qt creator. in qt creator it builds fine but running the sample application result in file not found. then if you look at the build dir qt creates you can see that the make file for Sample did not generate the Sample executeable. Please any help would be need been trying for a couple weeks now with no luck.
