Armadillo was not found, not including screenfitter inside DDECal

I dont know if its important but it happens when I compile https://git.astron.nl/eosc/prefactor3-cwl/-/blob/master/Docker/Dockerfile-base

[91mCMake Warning at CMakeLists.txt:77 (message):
  Armadillo was not found, not including screenfitter inside DDECal


[0m-- Could NOT find Armadillo (missing: ARMADILLO_LIBRARY ARMADILLO_INCLUDE_DIR) 

Despite this the compilation was successful.
