# This module can find FUSE Library
#
# 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()
