Comment (by hinder):

 One could use NO_BUILD in any case where the autodetection fails.  This
 could be, for example, if the library is installed in a system location
 for which the linker has been correctly configured but is not one of the
 locations that the library-thorn writer thought of.  For example, in
 Ubuntu, I found that libraries were installed in /usr/lib/x86_64-linux-gnu
 rather than /usr/lib.

 I disagree that we want to abort if ZLIB_DIR = NO_BUILD.  Currently, I set
 NO_BUILD because we cannot determine the correct directory, but the
 compiler and linker know it already.  Ideally, we would probe this case by
 compiling and running a test program, but we don't do that yet. Linking
 will not necessarily fail if we don't know the location; the linker might
 know this itself.
