+# FindXalanC
+# -----------
+#
+# Find the Apache Xalan-C++ XSL transform processor headers and libraries.
+#
+# Imported targets
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines the following :prop_tgt:`IMPORTED` targets:
+#
+# ``XalanC::XalanC``
+#   The Xalan-C++ ``xalan-c`` library, if found.
+#
+# Result variables
+# ^^^^^^^^^^^^^^^^
+#
+# This module will set the following variables in your project:
+#
+# ``XalanC_FOUND``
+#   true if the Xalan headers and libraries were found
+# ``XalanC_VERSION``
+#   Xalan release version
+# ``XalanC_INCLUDE_DIRS``
+#   the directory containing the Xalan headers; note
+#   ``XercesC_INCLUDE_DIRS`` is also required
+# ``XalanC_LIBRARIES``
+#   Xalan libraries to be linked; note ``XercesC_LIBRARIES`` is also
+#   required
+#
+# Cache variables
+# ^^^^^^^^^^^^^^^
+#
+# The following cache variables may also be set:
+#
+# ``XalanC_INCLUDE_DIR``
+#   the directory containing the Xalan headers
+# ``XalanC_LIBRARY``
+#   the Xalan library
