+## Find library with its headers
+
+The `find_library()` method can now also verify if the library's headers are
+found in a single call, using the `has_header()` method internally.
+
+```meson
+# Aborts if the 'z' library is found but not its header file
+zlib = find_library('z', has_headers : 'zlib.h')
+# Returns not-found if the 'z' library is found but not its header file
+zlib = find_library('z', has_headers : 'zlib.h', required : false)
+```
+
+Any keyword argument with the `header_` prefix passed to `find_library()` will
+be passed to the `has_header()` method with the prefix removed.
+
+```meson
+libfoo = find_library('foo',
+  has_headers : ['foo.h', 'bar.h'],
+  header_prefix : '#include <baz.h>',
+  header_include_directories : include_directories('.'))
+```
