* Suppress a warning in unsqueeze (#2637)

I keep getting this warning when building PyTorch:

This commit should fix it and modernize the code a bit.

* Use cmake GNUInstallDirs (#2661)

https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html
this make allow install the libraries (and headers) in different location than `lib` (Gentoo uses lib64 for 64-bits libs)
also change the .cmake files for avoid conclicts if build both 32-bis and 64-bits (avoids conflict/overwrite files)
