Error on a New Linux & QT5 install, No Such File Error

I am in the process of trying to build an existing QT project on a new Fedora Linux install and I am having some include path issues. I am a linux novice as well. The error I am getting is

/home/ken/Desktop/navstand_2022_8_1/include.h:62: error: labjackusb.h: No such file or directory
In file included from ../navstand_2022_8_1/prophylr.h:2,
                 from ../navstand_2022_8_1/main.cpp:3:
../navstand_2022_8_1/include.h:62:10: fatal error: labjackusb.h: No such file or directory
   62 | #include <labjackusb.h>
      |          ^~~~~~~~~~~~~~
  

which says in can not find the file in the angle brackets vs ""

The top part of the my QT pro file is below.

#-------------------------------------------------
#
# Project created by QtCreator 2013-11-17T14:33:09

QT       += core gui network serialport

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = navstand
TEMPLATE = app

LIBS += -lc -lqwt-qt5 -lm -lmodbus -llabjackusb -lusb-1.0 -lLabJackM
INCLUDEPATH += $(SYSROOT)/usr/include $(SYSROOT)/usr/local/include  $(SYSROOT)/usr/include/qt5 $(SYSROOT)/usr/include/libusb-1.0/ $(SYSROOT)/usr/include/qt5/qwt $(SYSROOT)/usr/lib64

SOURCES += main.cpp \
        command_fm6.cpp \

I can see the .h file at /usr/local/include below

[ken@fedora include]$ ls -al
total 96
drwxr-xr-x. 1 root root    20 Sep  8 22:02 .
drwxr-xr-x. 1 root root    90 Jan 19  2022 ..
-rwxr-xr-x. 1 root root 94786 Sep  8 22:02 LabJackM.h
[ken@fedora include]$ pwd
/usr/local/include

I have no environment variables in my QT project and I have not specifically created environment variable $(SYSROOT) since I don't know where to create it. In this case "I think" the $(SYSROOT) would almost be a blank variable which I have tried setting in the QT environment variable with no success. What should I do to correct my include path here?
