Hello @farges

Thank you for your contribution! A CUDA compiler can be ignored by setting the env variable:

export AIDGE_WITH_CUDA=OFF

The env variables are not documented which is IMO the real issue here.

Here is a quick attempt to make a table documenting them:

Variable	Default value	Description
AIDGE_INSTALL	<path to env> / lib / libAidge	Path to the installation folder of Aidge, must be the same used for all aidge dependencies
AIDGE_C_COMPILER	gcc	C Compiler to use
AIDGE_CXX_COMPILER	g++	CXX Compiler to use
AIDGE_BUILD_TYPE	Release	Can either be Release or Debug.
AIDGE_ASAN	OFF	Compile with ASAN for debug.
AIDGE_WITH_CUDA	ON	Compile CUDA kernel for quantization, requires nvcc and aidge_bakcend_cuda.
AIDGE_CMAKE_ARCH	""	Append architecture-specific arguments if provided.
AIDGE_BUILD_GEN	""	To specify a CMake generator (for example Ninja)

The list of these variables is defined in the setup.py

Maybe you can add this table to the README ?

@pineapple @bhalimi If you have comment on this table can you please tell me here and otherwise can you leave a thumbs up so that I hav eyour approbation?
