-FindLibXml2
------------
-
-Find the XML processing library (libxml2).
-
-IMPORTED Targets
-^^^^^^^^^^^^^^^^
-
-The following :prop_tgt:`IMPORTED` targets may be defined:
-
-``LibXml2::LibXml2``
- If the libxml2 library has been found
-``LibXml2::xmllint``
- If the xmllint command-line executable has been found
-
-Result variables
-^^^^^^^^^^^^^^^^
-
-This module will set the following variables in your project:
-
-``LibXml2_FOUND``
- true if libxml2 headers and libraries were found
-``LIBXML2_INCLUDE_DIR``
- the directory containing LibXml2 headers
-``LIBXML2_INCLUDE_DIRS``
- list of the include directories needed to use LibXml2
-``LIBXML2_LIBRARIES``
- LibXml2 libraries to be linked
-``LIBXML2_DEFINITIONS``
- the compiler switches required for using LibXml2
-``LIBXML2_XMLLINT_EXECUTABLE``
- path to the XML checking tool xmllint coming with LibXml2
-``LIBXML2_VERSION_STRING``
- the version of LibXml2 found (since CMake 2.8.8)
-
-Cache variables
-^^^^^^^^^^^^^^^
-
-The following cache variables may also be set:
-
-``LIBXML2_INCLUDE_DIR``
- the directory containing LibXml2 headers
-``LIBXML2_LIBRARY``
- path to the LibXml2 library
-#]=======================================================================]

-# in the find_path() and find_library() calls
