Can't seem to build on Arch Linux: FindLibObs.cmake not existing?

[RedrcknRbn]

When attempting to do cmake .., it gives the following result:

[redd@archlinux build]$ cmake ..

CMake Error at CMakeLists.txt:18 (find_package):
  By not providing "FindLibObs.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "LibObs", but
  CMake did not find one.

  Could not find a package configuration file provided by "LibObs" with any
  of the following names:

    LibObsConfig.cmake
    libobs-config.cmake

  Add the installation prefix of "LibObs" to CMAKE_PREFIX_PATH or set
  "LibObs_DIR" to a directory containing one of the above files.  If "LibObs"
  provides a separate development package or SDK, be sure it has been
  installed.

It seems like header files for OBS is missing. It's called libobs-dev in Debian, maybe there is some analogue for ArchLinux.

Someone suggested a workaround. The required changes are:

• Change LibObs to libobs at CMakeLists.txt
• Make sure /usr/include/obs is part of the include paths.

I'm not sure how the other OBS plugins handle those. I know both obs-move-transition and obs-ptz both use the lower-case libobs, but I couldn't find how the include paths are set (1) (2), mostly because I'm not familiar with CMake.

Checking the file list for both Arch's obs-studio and Debian's libobs-dev, I can see both include cmake/libobs/libobs* (lower-case libobs), and both install the C headers to /usr/include/obs/.
