Has anyone tried using libtorch and libmesh together and I wonder how to write makefile

[nuomi68]

Recently I tried to write programs using both libmesh and libtorch, but I couldn't write the makefile, and libtorch uses cmake, which confused me even more. Has anyone done the same job and wants to see how you write makefiles.

I noticed MOOSE had similar work, I tried copying MOOSE's makefile, libtorch didn't work.

# Conditional parts if the user wants to compile MOOSE with torchlib
#
ifeq ($(ENABLE_LIBTORCH),true)
	LIBTORCH_LIB := libtorch.$(lib_suffix)

  ifneq ($(wildcard $(LIBTORCH_DIR)/lib/$(LIBTORCH_LIB)),)
    # Enabling parts that have pytorch dependencies
    libmesh_CXXFLAGS += -DLIBTORCH_ENABLED

    # Adding the include directories, we use -isystem to silence the warning coming from
    # libtorch (which would cause errors in the testing phase)
    libmesh_CXXFLAGS += -isystem $(LIBTORCH_DIR)/include/torch/csrc/api/include
    libmesh_CXXFLAGS += -isystem $(LIBTORCH_DIR)/include

    # Dynamically linking with the available pytorch library
    libmesh_LDFLAGS += -Wl,-rpath,$(LIBTORCH_DIR)/lib
    libmesh_LDFLAGS += -L$(LIBTORCH_DIR)/lib -ltorch
  else
    $(error ERROR! Cannot locate any dynamic libraries of libtorch. Make sure to install libtorch (manually or using scripts/setup_libtorch.sh) and to run the configure --with-libtorch before compiling moose!)
