[CMake] cross-compiling for arm

[Gunter, Walter E]

I am using the arm-2008q3 toolchain and having some issues with compiling.
Doing a c++ compile for RT Linux,
I have setup the following in my main CMakeLists.txt

arm-none-linux-gnueabi-g++

cmake_minimum_required(VERSION 3.2)

project(enterprise CXX)

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_CXX_COMPILER /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-g++)
set(CMAKE_C_COMPILER /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-gcc)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_AR /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-ar)
set(CMAKE_FIND_ROOT_PATH /mnt/root)

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

set(COMPILE_FLAGS "-lrt -Wall -lpthread")

set(CROSS_COMPILE_INCLUDES /opt/toolchains/arm-2008q3/arm-none-linux-gnueabi/libc/usr/include/linux)
set(LOCAL_PROJECT_HEADER_INCLUDES ${CMAKE_CURRENT_SOURCE_DIR}/includes)

find_package(Threads)
add_subdirectory(src)

Here is the /src folder CMakeLists.txt



set(SOURCES  ${CMAKE_CURRENT_SOURCE_DIR}
files.cpp
)

include_directories("../includes")
set_source_files_properties(${SOURCES} PROPERTIES LANGUAGE CXX)

set(VENDOR_LIBRARY  mycan.c evgpio.c)
add_library(vendorLib ${VENDOR_LIBRARY})

set_target_properties(vendorLib PROPERTIES LINKER_LANGUAGE CXX)

add_executable(enterprise ${SOURCES})

target_link_libraries(enterprise vendorLib ${CMAKE_THREAD_LIBS_INIT} pthread event config pcan)



I am able to complete ../cmake, but when I run make, I get the following error:

arm-none-linux-gnueabi-g++: /home/wegunterjr/Documents/projects/Enterprise_Dev_cmake/src: linker input file unused because linking not done

Any thoughts?
