I was able to figure it out.
To keep the explanation simple... Since my projects are located a C:\CW, one must change the value of MQX_PATH (located in C/C++ Build > Build Variables) with a value of:
C:\Program Files\Freescale\Freescale MQX 3.6
(The old value was ${ProjDirPath}\..\..\..\..\..\..\.. )
Also, change the value of MQX_PATH (located at C/C++ General > Linked Resources) with:
C:\Program Files\Freescale\Freescale MQX 3.6
(The old value was and empty string, no value).
Please see attached images.
