CMake Warning (dev) at src/CMakeLists.txt:26 (ADD_LIBRARY):
  Policy CMP0028 is not set: Double colon in target name means ALIAS or
  IMPORTED target.  Run "cmake --help-policy CMP0028" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  Target "libliggghts" links to target "Qt5::Widgets" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?
This warning is for project developers.  Use -Wno-dev to suppress it.

The full build log is attached; please do let me know if the problem is
unreproducible, in which case I shall try to investigate further. As speculated
in #764833, however, this problem is most likely due to updates to cmake.

Best,
Michael
