FlowVR is missing FindPython3.cmake script to find Python3. The following error occurs:

Building FlowVR 2.2.0 (GIT Revision ).
CMAKE_BUILD_TYPE not set. Performance may be affected. Possible values are  Debug, Release, RelWithDebInfo or MinSizeRel
CMake Warning at flowvr/CMakeLists.txt:15 (FIND_PACKAGE):
  By not providing "FindPython3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Python3", but
  CMake did not find one.
  Could not find a package configuration file provided by "Python3" with any
  of the following names:
    Python3Config.cmake
    python3-config.cmake
  Add the installation prefix of "Python3" to CMAKE_PREFIX_PATH or set
  "Python3_DIR" to a directory containing one of the above files.  If
  "Python3" provides a separate development package or SDK, be sure it has
  been installed.

This script can be added to repository or cmake >= 3.12 should be required in build.
