cmake: now able to build with IPA with minor changes
For OpenCV videoio/cap_dshow.cpp, deactivate LTO for just that file.
Either with cmake or #pragma. Otherwise opening the camera causes a
crash in DShow machinery.
LibOVR build without LTO completely as there are some duplicate symbol
errors.
Other than that, LTO build seems to work fine.
