“没有规则可以成为目标”已经存在

Question

我正在尝试从源代码构建ROS，在我没有root访问权限的环境中，所以没有sudo apt-get。

rospack需要libtinyxml-dev，但我不能只安装该软件包。因此，我从源代码构建了TinyXML，并将其安装到~/usr/local/{lib, include}中。某些目标（例如xmlrpcpp，rosbuild）可以正常构建，但rospack会抛出a>

make[2]: *** No rule to make target '/home/USERNAME/usr/local/lib/libtinyxml.so', needed by 
'/home/USERNAME/ros_desktop/catkin_ws/devel/.private/rospack/lib/librospack.so'.  Stop.
但是，文件libtinyxml.so已经存在，并且是libtinyxml.so.2.6.2的符号链接，该文件也存在。我完全不知道该怎么办。我尝试过add_library(... SHARED IMPORTED)，通常喜欢CMakeLists.txt，但没有骰子。我怎样才能告诉CMake“嘿，这个库存在，只需链接它即可！”或者，如果错误实际上还意味着其他内容，那么会得到更多有用的错误？如果它已经存在，为什么要make库？感谢任何可以帮助我的人！
