How to specify the path of Boost

edit

I'm trying to cross-compile ROS Base from source.

I've cross-compiled the Boost 1.58.0 and installed it at /usr/local/boost, which contains include/boost and lib.

Also, I wrote

SET(BOOST_ROOT "/usr/local/boost")
SET(BOOST_INCLUDEDIR "/usr/local/boost/include")
SET(BOOST_LIBRARYDIR "/usr/local/boost/lib")

into the CMakeLists.txt of cpp_common, so it becomes as below:

cmake_minimum_required(VERSION 2.8.3)
project(cpp_common)

SET (BOOST_ROOT "/usr/local/boost")
SET (BOOST_INCLUDEDIR "/usr/local/boost/include")
SET (BOOST_LIBRARYDIR "/usr/local/boost/lib")

find_package(Boost REQUIRED COMPONENTS system thread)
find_package(console_bridge REQUIRED)
find_package(catkin REQUIRED)

And I created a file named test.cmake as below:

# this one is important
SET(CMAKE_SYSTEM_NAME Linux)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)

# Set the target architecture
set(CMAKE_LIBRARY_ARCHITECTURE arm-linux-gnueabihf)

# where is the target environment 
SET(CMAKE_FIND_ROOT_PATH "/usr/arm-linux-gnueabihf") # no slash "/" at the end

# specify the cross compiler
SET(CMAKE_C_COMPILER   /usr/bin/arm-linux-gnueabihf-gcc-5)
SET(CMAKE_CXX_COMPILER /usr/bin/arm-linux-gnueabihf-g++-5)

# Set compiler flag
SET(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")
SET(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")

# Have to set this one to BOTH, to allow CMake to find rospack
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

However, when I executed the command ./src/catkin/bin/catkin_make_isolated -DCMAKE_TOOLCHAIN_FILE=/home/zyh/ros_base/test2.cmake --install -DCMAKE_BUILD_TYPE=Release to compile the ROS, I still get the error:
