-# - Find fuse
-# Find the native fuse includes and library
+# This module can find FUSE Library
#
-# FUSE_INCLUDE_DIR - where to find fuse/fuse.h.
-# FUSE_LIBRARIES - List of libraries when using fuse.
-# FUSE_FOUND - True if fuse found.
+# Requirements:
+# - CMake >= 2.8.3
+#
+# The following variables will be defined for your use:
+# - FUSE_FOUND : was FUSE found?
+# - FUSE_INCLUDE_DIRS : FUSE include directory
+# - FUSE_LIBRARIES : FUSE library
+# - FUSE_DEFINITIONS : FUSE cflags
+# - FUSE_VERSION : complete version of FUSE (major.minor)
+# - FUSE_MAJOR_VERSION : major version of FUSE
+# - FUSE_MINOR_VERSION : minor version of FUSE
+#
+# Example Usage:
+#
+# 1. Copy this file in the root of your project source directory
+# 2. Then, tell CMake to search this non-standard module in your project directory by adding to your CMakeLists.txt:
+# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
+# 3. Finally call find_package() once, here are some examples to pick from
+#
+# Require FUSE 2.6 or later
+# find_package(FUSE 2.6 REQUIRED)
+#
+# if(FUSE_FOUND)
+# add_definitions(${FUSE_DEFINITIONS})
+# include_directories(${FUSE_INCLUDE_DIRS})
+# add_executable(myapp myapp.c)
+# target_link_libraries(myapp ${FUSE_LIBRARIES})
+# endif()
