undefined: _cxgo_offsetof

[BrownNPC]

I was trying to compile clay.h but the compiled code is calling this _cxgo_offsetof() function. for example
_cxgo_offsetof(Clay__Alignbool{}, "#member"))), arena))}

Steps to reproduce:

1. Download clay.h with debug tooling disabled
2. make a clay.c file with the following content:

#define CLAY_IMPLEMENTATION
#include "clay.h"

3. Run cxgo file clay.c
4. grep for _cxgo_offsetof for example on line 730:

func Clay__BoolArray_Allocate_Arena(capacity int32, arena *Clay_Arena) Clay__BoolArray {
	return Clay__BoolArray{capacity: capacity, length: 0, internalArray: (*bool)(Clay__Array_Allocate_Arena(capacity, uint32(unsafe.Sizeof(bool(false))), uint32(int32(_cxgo_offsetof(Clay__Alignbool{}, "#member"))), arena))}
}

here is the C code for the function:

Clay__BoolArray Clay__BoolArray_Allocate_Arena(int32_t capacity, Clay_Arena *arena) {
    return CLAY__INIT(Clay__BoolArray){.capacity = capacity, .length = 0, .internalArray = (bool *)Clay__Array_Allocate_Arena(capacity, sizeof(bool), CLAY__ALIGNMENT(bool), arena)};
}
