#
# Libxml2 cmake module.
# This module sets the following variables:
#
# ::
#
#   LIBXML2_FOUND              - True if libxml2 headers and libraries were found
#   LIBXML2_INCLUDE_DIR        - Directory where LibXml2 headers are located.
#   LIBXML2_INCLUDE_DIRS       - list of the include directories needed to use LibXml2.
#   LIBXML2_LIBRARY            - path to the LibXml2 library.
#   LIBXML2_LIBRARIES          - xml2 libraries to link against.
#   LIBXML2_DEFINITIONS        - the compiler switches required for using LibXml2.
#   LIBXML2_VERSION_MAJOR      - The major version of libxml2.
#   LIBXML2_VERSION_MINOR      - The minor version of libxml2.
#   LIBXML2_VERSION_PATCH      - The patch version of libxml2.
#   LIBXML2_VERSION_STRING     - version number as a string (ex: "2.3.4")
#   LIBXML2_MODULES            - whether libxml2 has dso support
#   LIBXML2_XMLLINT_EXECUTABLE - path to the XML checking tool xmllint coming with LibXml2
#
# The following targets are defined:
#
#   LibXml2::LibXml2          - the LibXml2 library
#   LibXml2::xmllint          - the xmllint command-line executable
