+FindLibLZMA
+-----------
+
+Find LZMA compression algorithm headers and library.
+
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+.. versionadded:: 3.14
+
+This module defines :prop_tgt:`IMPORTED` target ``LibLZMA::LibLZMA``, if
+liblzma has been found.
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``LIBLZMA_FOUND``
+ True if liblzma headers and library were found.
+``LIBLZMA_INCLUDE_DIRS``
+ Directory where liblzma headers are located.
+``LIBLZMA_LIBRARIES``
+ Lzma libraries to link against.
+``LIBLZMA_HAS_AUTO_DECODER``
+ True if lzma_auto_decoder() is found (required).
+``LIBLZMA_HAS_EASY_ENCODER``
+ True if lzma_easy_encoder() is found (required).
+``LIBLZMA_HAS_LZMA_PRESET``
+ True if lzma_lzma_preset() is found (required).
+``LIBLZMA_VERSION_MAJOR``
+ The major version of lzma
+``LIBLZMA_VERSION_MINOR``
+ The minor version of lzma
+``LIBLZMA_VERSION_PATCH``
+ The patch version of lzma
+``LIBLZMA_VERSION_STRING``
+ version number as a string (ex: "5.0.3")
