failed to build tiramisu

[Abderrahmene-KSM]

When trying to build tiramisu , and after ruining the following command :
cmake . -B build -DISL_LIB_DIRECTORY=$ISL_LIB_DIRECTORY -DISL_INCLUDE_DIRECTORY=$ISL_INCLUDE_DIRECTORY -DPython3_EXECUTABLE=which python3
I am getting this error :
CMake Error at CMakeLists.txt:83 (find_package):
By not providing "FindHalide.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Halide", but
CMake did not find one.

Could not find a package configuration file provided by "Halide" with any
of the following names:

HalideConfig.cmake
halide-config.cmake

Add the installation prefix of "Halide" to CMAKE_PREFIX_PATH or set
"Halide_DIR" to a directory containing one of the above files. If "Halide"
provides a separate development package or SDK, be sure it has been
installed.

Can you follow "Method 3" to install Tiramisu as described in the Readme file

I got the same error, and I tried the 3rd approach, but I got the following error:
"fatal: Needed a single revision
fatal: Unable to find current origin/master revision in submodule path '3rdParty/Halide'".
Also, I couldn't install using spack.
