How important is the order of columns in indexes?
...tioned in one Answer.
So, what order should be used?
Start with column(s) tested with =, in any order.
Then tack on one range column.
For example, the very-low selectivity column must come first in this:
WHERE deleted = 0 AND the_datetime > NOW() - INTERVAL 7 DAY
INDEX(deleted, the_datetime)

Why should I not include cpp files and instead use a header?
... 1, that means you have to compile all two million lines again in order to test this. And if you find out that you meant to do a x = y - 1 instead, then again, two million lines of compile are waiting for you. That's many hours of time wasted that could be better spent doing anything else.

What is ?= in Makefile
... not set/doesn't have a value.
For example:
KDIR ?= "foo"
KDIR ?= "bar"
test:
echo $(KDIR)
Would print "foo"
