# If you are cloning and compiling the libigl repository as a standalone, you
# can use this file as a convenience to set default CMake options. Simply copy
# this file and remove the '.sample' suffix. Then, uncomment the relevant
# options as desired. Note that this file is included before `project(Libigl)`
# is defined, so we can use it to define the C and C++ compilers, but some
# variables such as PROJECT_SOURCE_DIR will not be defined yet. You can use
# CMAKE_SOURCE_DIR instead.
#
# If you are using libigl as a subproject (e.g. see the libigl-example-project
# template), then you do NOT need to use this file. Simply set your preferred
# CMake options in the parent project, # before including libigl.
