OpenBangla fails to build on openSUSE MicroOS (Kalpa)

[Dyrimon]

I'm trying to build the develop branch on Kalpa, cmake error fails to find rust.

~/OpenBangla-Keyboard/build> sudo cmake .. -DCMAKE_INSTALL_PREFIX="/usr"
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
