So I'm building a simple MikroC program that sets PORTB.B0 if PORTA.B0 is equaled to 1

void main() {
   PORTA.B0=1;
   while(1){
   if(PORTA.B0){
        PORTB.B0=1;
   }
   }
}

However it doesn't give me anything PortB.B0 isn't equal to 1 only portA.

Can anyone help?

According to your code you, you must have initialized the direction of the portb.rb0 and porta.ra0 bits as output and input respectively. Also you need to give a little delay for de-bouncing.

void main()
{
ANSEL=0x00;
trisa.ra0=1; //for input
trisb.rb0=0; //for output
while(1)
{
   if (porta.ra0)
   {
     portb.rb0=1;  // setting high
     delay_ms(300); // time to stabilize mechanical button
    }
}

Just try if(PORTA.B0==1). This should work.
