I am challenging Cmake to use both Realsense and PCL with reference to this page. https://github.com/IntelRealSense/librealsense/tree/master/wrappers/pcl

However, I get the following error and I can not configure it. CMake Error at D:/ProgramFiles/CMake/share/cmake-3.12/Modules/ExternalProject.cmake:2324 (message): error: could not find git for clone of libusb

Although the URL of libusb is present, it seems that the directory can not be found, but what is the problem?

Hi @Ace-242 I believe what is missing is git installed on the system. You can resolve this for now by unchecking BUILD_WITH_TM2 flag in CMake UI.

Hi dorodnic. Thank you! Thanks to you I solved the problem.

Could you tell me why you can do this once unchecking "BUILD_WITH_TM2" this for future study?

[dorodnic]

At the moment, to support the TM2 (T265) device we need libusb. Since there is no packaged version available on Windows, our CMake will pull latest version from official GitHub and build it for you. This requires git. However, TM2 modules are not yet available for purchase to the general public, so unless you received one via our partners program, you don't really need it in librealsense for now.

Thanks to you I understood.

Hi, I'm sorry to "reopen" this issue, but I encounter the same issue, and even while unchecking BUILD_WITH_TM2, I get the same issue. What should I do to troubleshoot?

Hi, as I also commented on #2719 , I have been able to solve this issue on my machine.
