The return value of cmd2 WILL be ignored here. cmd2 might still generate
error messages but it will not cause make to fail because make is only
interested in the last return code of each shell command (in this case, that
of cmd3).
That said, you can explicitly force the return code to be 0 with:
all:
cmd1 ; cmd2 || true ; cmd3
but that won't, in this case, have any effect on the make execution.
Likewise:
all:
cmd1
cmd2 || true
cmd3
would fail if either cmd1 or cmd3 failed, but will ignore a failure for
cmd2.
