  Invalid character escape '\l'.

Yep, #17939 is broken on Windows. You can submit a PR to fix these paths by adding .replace("\\", "/") when there are passed to toolchain variables.

Basically instead of:

        if self._tbbbind_explicit_hwloc:
            hwloc_package_folder = self.dependencies["hwloc"].package_folder.replace("\\", "/")
            hwloc_lib_name = "hwloc.lib" if self.settings.os == "Windows" else "libhwloc.so"
            toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_LIBRARY_PATH"] = os.path.join(hwloc_package_folder, "lib", hwloc_lib_name)
            toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_INCLUDE_PATH"] = os.path.join(hwloc_package_folder, "include")
            if self.settings.os == "Windows":
                toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_DLL_PATH"] = os.path.join(hwloc_package_folder, "bin", "hwloc.dll")

it should be:

        if self._tbbbind_explicit_hwloc:
            hwloc_package_folder = self.dependencies["hwloc"].package_folder
            hwloc_lib_name = "hwloc.lib" if self.settings.os == "Windows" else "libhwloc.so"
            toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_LIBRARY_PATH"] = os.path.join(hwloc_package_folder, "lib", hwloc_lib_name).replace("\\", "/")
            toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_INCLUDE_PATH"] = os.path.join(hwloc_package_folder, "include").replace("\\", "/")
            if self.settings.os == "Windows":
                toolchain.variables[f"CMAKE_HWLOC_{self._tbbbind_hwloc_version}_DLL_PATH"] = os.path.join(hwloc_package_folder, "bin", "hwloc.dll").replace("\\", "/")

The toolchain generator should be fixed to escape paths.
