Crossworks Compiler Error

Hello I am new to the Crossworks ARM complier and the the ARM Microcontrollers. I decided to use the NXP LPC2101 microcontroller and learn it. I downloaded the Crossworks ARM Compiler. I downloaded the following packages:

A) Crossworks Tasking Library Package.

B) NXP LPC2000 CPU Support Package.

I created a new project using the following steps:

1) File -> New Project

2) Choose: An Executable for NXP LPC2100 and Next

3) Choose: Additional Output Format: hex and Target Processor: LPC2101 and Finish

4) In the sources folder I created main.c file and wrote the following code in it:

#include <targets/LPC2000.h>
#include <targets/liblpc2000.h>

void main()
{
  GPIO0_IODIR |= (1<<10);
  GPIO0_IOSET |= (1<<10);
}

I get the following errors when I build the project:

'GPIO0_IODIR' undeclared (first use in this function)

each undeclared identifier is reported only once for each function it appears in

'GPIO0_IOSET' undeclared (first use in this function)

I have the following questions. First am I using the correct header files that include the names of the registers of the LPC2101? How can I solve the compiler error.

Thank You
