我有一个Qt项目，我正在尝试使用CMake进行构建。但是在运行make -j4命令时遇到了一些错误。
Error: CMakeFiles/QtCreator.dir/build.make:89: recipe for target 'QtCreator-prefix/src/QtCreator-stamp/QtCreator-download' failed
make[2]: *** [QtCreator-prefix/src/QtCreator-stamp/QtCreator-download] Error 1
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/QtCreator.dir/all' failed
make[1]: *** [CMakeFiles/QtCreator.dir/all] Error 2
Makefile:94: recipe for target 'all' failed
make: *** [all] Error 2
我正在使用cmake版本3.5.1 Ubuntu 16.04
