Error in migrating from Makefile to CMake - boost

Question

I have a library which compile without error using Makefile.
Now I want to switch to CMake but it doesn't work.
The sources and the Makefiles are here.
From all the folders I have kept the followin: can_socket, can_virtual, timers_xeno, timers_rtpreempt, timers_unix, unix.
This is my CMakeLists:
cmake_minimum_required(VERSION 2.4.6)
project(ikarus_arm_common C CXX)
#set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
find_package(Boost COMPONENTS filesystem system serialization REQUIRED)
set(CAN_MASTER_INCLUDE_DIR include)
include_directories( ${Boost_INCLUDE_DIRS}
${CAN_MASTER_INCLUDE_DIR}
${CAN_MASTER_INCLUDE_DIR}/boost
${CAN_MASTER_INCLUDE_DIR}/timers_rtpreempt
${CAN_MASTER_INCLUDE_DIR}/timers_unix
${CAN_MASTER_INCLUDE_DIR}/timers_xeno
${CAN_MASTER_INCLUDE_DIR}/unix
/usr/xenomai/include
)
set(CAN_FESTIVAL_CPP drivers/unix/unix.c
drivers/timers_xeno/timers_xeno.c
drivers/can_socket/can_socket.c
)
add_library(canfestival ${CAN_FESTIVAL_CPP})
EDIT:
When I try to compile it returns the following error:
> $ make

I suppose that one of the problems is due to the fact that some files have the extension .c but requires boost. If i modify the extension of the files unix.cpp and can_socket.cpp compile, while timers_xeno returns an error:

How can I fix this problem?
