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")
