FindFUSE.cmake 5.21 KiB
1 
# This module can find FUSE Library
2 
#
3 
# Requirements:
4 
# - CMake >= 2.8.3
5 
#
6 
# The following variables will be defined for your use:
7 
# - FUSE_FOUND : was FUSE found?
8 
# - FUSE_INCLUDE_DIRS : FUSE include directory
9 
# - FUSE_LIBRARIES : FUSE library
10 
# - FUSE_DEFINITIONS : FUSE cflags
11 
# - FUSE_VERSION : complete version of FUSE (major.minor)
12 
# - FUSE_MAJOR_VERSION : major version of FUSE
13 
# - FUSE_MINOR_VERSION : minor version of FUSE
14 
#
15 
# Example Usage:
16 
#
17 
# 1. Copy this file in the root of your project source directory
18 
# 2. Then, tell CMake to search this non-standard module in your project directory by adding to your CMakeLists.txt:
19 
# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
20 
# 3. Finally call find_package() once, here are some examples to pick from
21 
#
22 
# Require FUSE 2.6 or later
23 
# find_package(FUSE 2.6 REQUIRED)
24 
#
25 
# if(FUSE_FOUND)
26 
# add_definitions(${FUSE_DEFINITIONS})
27 
# include_directories(${FUSE_INCLUDE_DIRS})
28 
# add_executable(myapp myapp.c)
29 
# target_link_libraries(myapp ${FUSE_LIBRARIES})
30 
# endif()
