I tried to install the PoseLib with pip however there is no the compiled version on pypi website. And then I tried install with conan, followed the instructions in the installation section, however again, the mysterious thing is that the poselib can be found in pip when execute the commond under the PoseLib source code folder, but cannot work when exited the source code foler.

As you can see, the conan installation is successful, and execute the "pip list | grep pose", it works under the folder of "PoseLib", but not out of it, strange isn't it?
