If anyone would like to integrate MFEM through conan, here is a conanfile:

from conan import ConanFile
from conan.tools.cmake import CMake, CMakeToolchain, CMakeDeps, cmake_layout
from conan.tools.files import get, rmdir, copy
import os

class Package(ConanFile):
    name = "mfem"
    version = "4.7"
    description = "Modular finite element library for scalable scientific computing"
    license = "BSD-3-Clause"
    url = "https://github.com/mfem/mfem"
    settings = "os", "compiler", "build_type", "arch"
    options = {
        "shared": [True, False],
        "mpi": [True, False],
        "hypre": [True, False],
        "metis": [True, False],
        "suite_sparse": [True, False],
    }
    default_options = {
        "shared": False,
        "mpi": False,
        "hypre": False,
        "metis": False,
        "suite_sparse": False,
    }

    def requirements(self):
        # Add required dependencies
        if self.options.mpi:
            self.requires("mpi/1.0")
        if self.options.hypre:
            self.requires("hypre/2.23.0")
        if self.options.metis:
            self.requires("metis/5.1.0")
        if self.options.suite_sparse:
            self.requires("suite-sparse/5.10.1")

    def source(self):
        get(self, f"https://github.com/mfem/mfem/archive/refs/tags/v{self.version}.tar.gz", strip_root=True)

    def layout(self):
        cmake_layout(self)

    def generate(self):
        tc = CMakeToolchain(self)
        tc.variables["MFEM_USE_MPI"] = "ON" if self.options.mpi else "OFF"
        tc.variables["MFEM_USE_METIS"] = "ON" if self.options.metis else "OFF"
        tc.variables["MFEM_USE_SUITESPARSE"] = "ON" if self.options.suite_sparse else "OFF"
        tc.variables["BUILD_SHARED_LIBS"] = "ON" if self.options.shared else "OFF"
        tc.generate()
        deps = CMakeDeps(self)
        deps.generate()

    def build(self):
        cmake = CMake(self)
        cmake.configure()
        cmake.build()

    def package(self):
        cmake = CMake(self)
        cmake.install()
        rmdir(self, os.path.join(self.package_folder, "lib", "cmake"))
        rmdir(self, os.path.join(self.package_folder, "lib", "pkgconfig"))
        copy(self, "LICENSE.txt", self.source_folder, os.path.join(self.package_folder, "licenses"))


    def package_info(self):
        self.cpp_info.libs = ["mfem"]
        if self.options.mpi:
            self.cpp_info.defines.append("MFEM_USE_MPI")

Just a small remark: there is no config option MFEM_USE_HYPRE -- the use of hypre is controlled by MFEM_USE_MPI.
