FYI 2.53.1 is the last version that supports the following cameras: R300, T265, T261, L515.

Hi, git is still needed to clone libcurl:

-- Building libcurl enabled
CMake Error at /usr/share/cmake/Modules/ExternalProject.cmake:2806 (message):

Also, please remove the leading v in pkgver. And glu should be added as a dependency.

Hi, is there a particular reason for not to use https://github.com/IntelRealSense/librealsense/archive/refs/tags/v${pkgver}.tar.gz as source?

This has a remarkably bad performance for me. If I run rs-depth on my PC it is using 200% processor time in top, while on a raspberry (of all things) it can do the same thing using only 50% processor time. My own test program cannot grab 30 fps at 1280 x 720. Instead I get 15 fps. On the raspberry it does get 30 fps while using less processor time.

Edit: It appears that I was accusing this library falsely. Turned out that I still had another, much older, version of librealsense on my computer and it was using that one. This one seems to do fine. But I did find that to get metadata I had to add -DFORCE_RSUSB_BACKEND=true to the options of cmake.

if someone has the same problem as acmiyaguchi feel free to use this patch: https://github.com/muellerbernd/my_arch_packages/blob/master/librealsense/include_dir.patch

I had (and still) have issues with using this inside of a catkin workspace.

When building against realsense-ros (https://github.com/IntelRealSense/realsense-ros), I get the following error in realsense2_camera:

CMake Error at /lib64/cmake/realsense2/realsense2Config.cmake:11 (message):
  File or directory //include referenced by variable realsense2_INCLUDE_DIR
  does not exist !
Call Stack (most recent call first):
  /lib64/cmake/realsense2/realsense2Config.cmake:33 (set_and_check)
  CMakeLists.txt:44 (find_package)

I resolved this by manually going into /lib64/cmake/realsense2/realsense2Config.cmake and replacing statement setting PACKAGE_PREFIX_DIR to the following:

set(PACKAGE_PREFIX_DIR /usr)

This part of the configuration is set by the following lines:

https://github.com/IntelRealSense/librealsense/blob/5ff27fca5aaeec4736d6bb3bfb958fee82ee198b/CMake/install_config.cmake#L11-L15

Not sure why the PACKAGE_PREFIX_DIR is invalid, would be nice to have this package install cleanly though.

@pingplug Understood, I apologise for my misconception and thank you very much for the info.

@Svanto I can't run realsense-viewer with glfw-wayland.

Is there a technical reason that the package does not allow to use glfw-wayland in place of glfw-x11 as a dependency? I cannot seem to find one. If there is not, may I request that it's added as an alternative?

Thank you very much for your time.
