Subject: [PATCH] Makefile: fix invoking cmake in the build dir (#2078)

`"(@D)"` is the dir of the target, i.e. "build" for BUILDDIR=build,
which results in calling `cmake build ..`.

cmake appears to ignore the "build" in this case, and works the same way
without it.

Instead of ".." this patch uses `$(CURDIR)`, which is the absolute path
to the source dir, which is relevant in case `BUILDDIR` is not just a
direct subdirectory.
