[Solved] Errors Building 2.3.0-alpha0 on Linux  

Errors Building 2.3.0-alpha0 on Linux

I am trying to build the latest alpha on Linux but am stuck on an error that I havent been able to find anything on. I have been working through dependency errors but seem to have gotten those taken care of. Now I am getting an error when it is trying to work with CGAL. I do see there is a CGAL.cmake file included but that doesnt seem to be what it is looking for. Any assistance would be appreciated. Or if more information is needed please let me know. I am on Ubuntu 20.04 LTS

  By not providing "FindCGAL.cmake" in CMAKE_MODULE_PATH this project has

  asked CMake to find a package configuration file provided by "CGAL", but

  CMake did not find one.



  Could not find a package configuration file provided by "CGAL" with any of

  Add the installation prefix of "CGAL" to CMAKE_PREFIX_PATH or set

  "CGAL_DIR" to a directory containing one of the above files.  If "CGAL"

  provides a separate development package or SDK, be sure it has been

  installed.
