[AMBER] Query regarding AMBER24 - "KMMD" CMAKE ERROR - Requesting clarification.

While installing AMBER24 for GPU-based MD simulations, this error was
displayed after ./run_cmake command:
CMake Error at AmberTools/src/kmmd/CMakeLists.txt:15 (add_library):
  add_library cannot create target "kmmd" because another target with the
  same name already exists. The existing target is an interface library
  created in source directory "/home/<directory name>/pmemd24_src". See
documentation
  for policy CMP0002 for more details.
I have tried downloading the amber installation zip again and, cleaning the
build folder and restarting the installation process but these did not help
at all. The only thing that helped with continuing the cmake process was by
changing the /home/<directory
name>/pmemd24_src/AmberTools/src/kmmd/CMakeLists.txt file by putting the
"add_library(kmmd ${KMMD_SOURCE})" line in an if loop, like this:
if(NOT TARGET kmmd)
    add_library(kmmd ${KMMD_SOURCE})
endif()
Could any clarification be given if this editing was okay?
