Changes in Cmakelists.txt broke rpm build & install process on Linux

I encounter two problems:

1. library installation path changed from the usual /usr/lib (I am OK with that) to /usr/lib + /usr/lib64 + /usr/lib64libsurvive

ls -R

./lib:
debug  libminimal_opencv.a  libmpfit.a

./lib/debug:
usr

./lib/debug/usr:
bin  lib64  lib64libsurvive

./lib/debug/usr/bin:
api_example.debug  sensors-readout.debug  survive-buttons.debug  survive-cli.debug  survive-solver.debug

./lib/debug/usr/lib64:
libsurvive.so.0.3.debug  libsurvive.so.0.debug  libsurvive.so.debug

./lib/debug/usr/lib64libsurvive:
plugins

./lib/debug/usr/lib64libsurvive/plugins:
disambiguator_statebased.so.debug  driver_global_scene_solver.so.debug  driver_simulator.so.debug  driver_vive.so.debug            poser_kalman_only.so.debug
driver_dummy.so.debug              driver_openvr.so.debug               driver_udp.so.debug        poser_barycentric_svd.so.debug  poser_mpfit.so.debug
driver_gatt.so.debug               driver_playback.so.debug             driver_usbmon.so.debug     poser_dummy.so.debug

./lib64:
libsurvive.so  libsurvive.so.0  libsurvive.so.0.3  pkgconfig

./lib64/pkgconfig:
survive.pc

./lib64libsurvive:
plugins

./lib64libsurvive/plugins:
disambiguator_statebased.so  driver_gatt.so                 driver_openvr.so    driver_simulator.so  driver_usbmon.so  poser_barycentric_svd.so  poser_kalman_only.so
driver_dummy.so              driver_global_scene_solver.so  driver_playback.so  driver_udp.so        driver_vive.so    poser_dummy.so            poser_mpfit.so

2. etc/bash_completion.d/survive_autocomplete.sh is not getting installed at all because it cannot find /etc/bash_completion.d. This folder does exist in the target system, but the installation is done to a temporary empty dir used only for rpm packaging instead of the root. The temporary dir will never have etc/bash_completion.d subdir (before it is created by the cmake install itself). A manually set flag would be better for rpm packaging.

This patch fixes the build for me: libsurvive-makefiles.patch.txt
