client/fuse_ll.cc is now including <fuse.h> and <fuse_lowlevel.h> instead of <fuse/fuse.h> and <fuse/fuse_lowlevel.h>, so we need to add the fuse directory to the FUSE_INCLUDE_DIRS variable using find_path() with just fuse.h was finding a /usr/include/fuse.h instead of the one in /usr/include/fuse/. looking for fuse_common.h and fuse_lowlevel.h first causes it to generate the correct FUSE_INCLUDE_DIRS=/usr/include/fuse Fixes: #12909 Signed-off-by: Casey Bodley <cbodley@redhat.com>

# 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()
