CMakeLists.txt

# This CMakeLists.txt file is useful when compiling SCIANTIX with the cmake tool
#
# output:
#   > build directory with executable in build/sciantix.x
#
# When using IDE, a CMakeSettings.json could be automatically produced to compile sciantix in a locall out/build/ folder
# by setting this file as startup element.
