# This CMake file is written specifically to integrate qhull library with Slic3rPE
# (see https://github.com/prusa3d/PrusaSlicer for more information about the project)
#
# Only original libraries qhullstatic_r and qhullcpp are included.
# They are built as a single statically linked library.
#
# Created by modification of the original qhull CMakeLists.
