the proper way is to use CPPFLAGS="-DPD_FLOAT_PRECISION=64",
But now you undo the CPPFLAGS as defined in the makefile. I didn't know how to add to the CFLAGS from the command line, but found a solution here:

It requires a small adaptation to the makefile. Instead of:
CFLAGS = ....
comes:
override CFLAGS += .....
Now you can add to CFLAGS from the command line, like so:
make CFLAGS="-DPD_FLOAT_PRECISION=64"
Note that the CFLAGS in the makefile now have precedence and you can only add to it from the command line, not override it.
