将cmake/pcl_find_boost.cmake文件里的

# Required boost modules  
find_package(Boost 1.40.0 REQUIRED COMPONENTS system filesystem thread date_time iostreams) 

修改为

# Required boost modules  
find_package(Boost 1.40.0 REQUIRED COMPONENTS system filesystem thread date_time iostreams chrono)  

cmake/pcl_find_boost.cmake文件中相应内容为

# Required boost modules  
set(BOOST_REQUIRED_MODULES system filesystem thread date_time iostreams)  
# Starting with Boost 1.50, boost_thread depends on chrono. As this is not  
# taken care of automatically on Windows, we add an explicit dependency as a  
# workaround.  
if(WIN32 AND Boost_VERSION VERSION_GREATER "104900")  
  set(BOOST_REQUIRED_MODULES ${BOOST_REQUIRED_MODULES} chrono)  
endif(WIN32 AND Boost_VERSION VERSION_GREATER "104900")
