USE_SYSTEM_LIBUSB does not exists in lrs_options.cmake

[oiramario]

The default settings of wiki "Build Customization Flags" are not synchronized with lrs_options.

Updated, thanks :)
Build-Configuration

[oiramario]

Thanks~ Glad to see your update!
However, there are 30 macros in Build-Configuration and 26 macros in lrs_options.cmake.

Build-Configuration------------------------------lrs_options.cmake
BUILD_PYTHON_MATLAB------------------------mismatch BUILD_MATLAB_BINDINGS
DOTNET_VERSION_EXAMPLES------------------missing
DOTNET_VERSION_LIBRARY---------------------missing
BUILD_CV_KINFU_EXAMPLES--------------------missing
INTERNAL_FW_SOURCE-------------------------missing
USE_SYSTEM_LIBUSB----------------------------missing
CMAKE_BUILD_TYPE-----------------------------ignore

[dorodnic]

Yes, we should try to collect everything into lrs_options.cmake.
Recent Cmake refactor was a big step forward IMHO, and I certainly don't want to go back to the spaghetti Cmake we used to have until recently.

pls add USE_SYSTEM_LIBUSB into lrs_options.cmake, because:

macro--------------------------------Build-Configuration----------lrs_options.cmake
BUILD_WITH_OPENMP------------------true------------------------------off
USE_SYSTEM_LIBUSB -------------------true------------------------------missing

I'm also interested in having USE_SYSTEM_LIBUSB as ExternalProject_Add(libusb ...) custom target sometimes fails on windowsusing Ninja build with

fatal: could not create work tree dir 'libusb': Permission denied
fatal: could not create work tree dir 'libusb': Permission denied
fatal: could not create work tree dir 'libusb': Permission denied
-- Had to git clone more than once:
          3 times.
CMake Error at C:/Users/cfantacci/GitHub/librealsense/buildprova/libusb-prefix/tmp/libusb-gitclone.cmake:66 (message):
  Failed to clone repository: 'https://github.com/libusb/libusb.git'

To workaround this problem you just need to run ninja twice. I tried to had a look into it, but found no solution.

@dorodnic Do we have any plan to include USE_SYSTEM_LIBUSB option?

@oiramario Could you please check the latest SDK v2.26? lrs_options.cmake and the related wiki doc are updated. Looking forward to your feedback. Thanks!
