# 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
