When I build the project on my Gentoo-Linux 4.8.2 with cmake , there was a build error when I wanna build the target lesson_l2_using_the_gpu.cpp.o :
" undefined reference to symbol 'dlopen@@GLIBC_2.2.5' " and then I have to track the build error,finally I found the link txt of cmake_build/tutorial/CMakeFiles/lesson_12_using_the_gpu.dir/link.txt here : /usr/bin/c++ CMakeFiles/lesson_12_using_the_gpu.dir/lesson_12_using_the_gpu.cpp.o -o ../bin/lesson_12_using_the_gpu -rdynamic ../lib/libHalide.so -lpng -lz -Wl,-rpath,/home/elvis/environment/Halide/github/Halide/cmake_build/lib
and now I change the build option , add the -ldl like that :
/usr/bin/c++ CMakeFiles/lesson_12_using_the_gpu.dir/lesson_12_using_the_gpu.cpp.o -o ../bin/lesson_12_using_the_gpu -rdynamic ../lib/libHalide.so -lpng -lz -ldl -Wl,-rpath,/home/elvis/environment/Halide/github/Halide/cmake_build/lib
which finally build completely. I don't know whether It was caused by my environment , because I consider my environment was customized by myself using the Gentoo's build script. And there is some of my build environment :

I ever think that the error was caused by the version of my GCC version when I use the GCC-5.4.0 , and then I compile the world with GCC-4.8.5 , which wasted my lots of time , and now I have to compile the world with GCC-5.4.0 again . T_T .
