You don't need to use a PIC that has a LCD driver module in it, like the
16F914 to use an LCD module such as the 8x2 Crystalfontz unit.

The 16F914 PIC is meant to drive a segmented LCD like this one:
http://www.varitronix.com/20060310/catalog/lcd_spec/VI402.PDF
The PIC drives the individual segments of that LCD.

The Crystalfontz LCD module that you're using has a controller built
into the unit. It has a microcontroller interface. Any PIC that has
at least 6 i/o pins can talk to the the Crystalfontz LCD. You don't
use the LCD driver in the 16F914 to talk to the Crystalfontz LCD.
You just use the CCS LCD.C driver.

So instead of doing this:
setup_lcd(LCD_STATIC);

You should do this:
setup_lcd(LCD_DISABLED);
