So I went past this step and able to include it in my project.

But I see the following warning

[16/247] Compiling C object libccan.a.p/ccan_bitmap_bitmap.c.o
In file included from ../ccan/bitmap/bitmap.c:5:
../ccan/bitmap/bitmap.h: In function bitmap_set_bit:
../ccan/bitmap/bitmap.h:61:43: warning: declaration of bitmap shadows a global declaration [-Wshadow]

   26 | } bitmap;
      |   ^~~~~~


If I were to change the parameter name to _bitmap and in all usages the
warning disappears. Weird the definition its pointing to is this typedewf


/*

typedef struct _bitmap {
	bitmap_word w;
} bitmap;
