+
+A few useful options:
+- `./configure --without-cuda` in order to build the CPU part only.
+- `./configure --with-cuda=/path/to/cuda-10.1` in order to hint to the path of
+the cudatoolkit.
+- `./configure --with-cuda-arch="-gencode=arch=compute_75,code=sm_75 -gencode=arch=compute_72,code=sm_72"` for specifying which GPU architectures to build against.
+- `./configure --with-python=/path/to/python3.7` in order to build a python
+interface for a different python than the default one.
+
+2. `make`
+
+This builds the C++ library (the whole library if a suitable cuda toolkit was
+found, or the CPU part only otherwise).
+
+3. `make install` (optional)
+
+This installs the headers and libraries.
+
+4. `make -C python` (or `make py`)
+
+This builds the python interface.
+
+5. `make -C python install`
+
+This installs the python library.

-   Flags/methods for returning states.
-
-   The SWIG conversion methods, as ConvertPtr, return an integer
-   that tells if the conversion was successful or not. And if not,
-   an error code can be returned (see swigerrors.swg for the codes).
-
-   Use the following macros/flags to set or process the returning
-   states.
-
-   In old versions of SWIG, code such as the following was usually written:
-
-     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
-       // success code
-     } else {
-       //fail code
-     }
-
-   Now you can be more explicit:
-
-    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-    } else {
-      // fail code
-    }
-
-   which is the same really, but now you can also do
-
-    Type *ptr;
-    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-      if (SWIG_IsNewObj(res) {
-        ...
-	delete *ptr;
-      } else {
-        ...
-      }
-    } else {
-      // fail code
-    }
-
-   I.e., now SWIG_ConvertPtr can return new objects and you can
-   identify the case and take care of the deallocation. Of course that
-   also requires SWIG_ConvertPtr to return new result values, such as
-
-      int SWIG_ConvertPtr(obj, ptr,...) {
-        if (<obj is ok>) {
-          if (<need new object>) {
-            *ptr = <ptr to new allocated object>;
-            return SWIG_NEWOBJ;
-          } else {
-            *ptr = <ptr to old object>;
-            return SWIG_OLDOBJ;
-          }
-        } else {
-          return SWIG_BADOBJ;
-        }
-      }
-
-   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
-   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
-   SWIG errors code.
-
-   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
-   allows to return the 'cast rank', for example, if you have this
-
-       int food(double)
-       int fooi(int);
-
-   and you call
-
-      food(1)   // cast rank '1'  (1 -> 1.0)
-      fooi(1)   // cast rank '0'
-
-   just use the SWIG_AddCast()/SWIG_CheckState()

-/* -----------------------------------------------------------------------------
- * Type initialization:
- * This problem is tough by the requirement that no dynamic
- * memory is used. Also, since swig_type_info structures store pointers to
- * swig_cast_info structures and swig_cast_info structures store pointers back
- * to swig_type_info structures, we need some lookup code at initialization.
- * The idea is that swig generates all the structures that are needed.
- * The runtime then collects these partially filled structures.
- * The SWIG_InitializeModule function takes these initial arrays out of
- * swig_module, and does all the lookup, filling in the swig_module.types
- * array with the correct data and linking the correct swig_cast_info
- * structures together.
- *
- * The generated swig_type_info structures are assigned statically to an initial
- * array. We just loop through that array, and handle each type individually.
- * First we lookup if this type has been already loaded, and if so, use the
- * loaded structure instead of the generated one. Then we have to fill in the
- * cast linked list. The cast data is initially stored in something like a
- * two-dimensional array. Each row corresponds to a type (there are the same
- * number of rows as there are in the swig_type_initial array). Each entry in
- * a column is one of the swig_cast_info structures for that type.
- * The cast_initial array is actually an array of arrays, because each row has
- * a variable number of columns. So to actually build the cast linked list,
- * we find the array of casts associated with the type, and loop through it
- * adding the casts to the list. The one last trick we need to do is making
- * sure the type pointer in the swig_cast_info struct is correct.
- *
- * First off, we lookup the cast->type name to see if it is already loaded.
- * There are three cases to handle:
- *  1) If the cast->type has already been loaded AND the type we are adding
- *     casting info to has not been loaded (it is in this module), THEN we
- *     replace the cast->type pointer with the type pointer that has already
- *     been loaded.
- *  2) If BOTH types (the one we are adding casting info to, and the
- *     cast->type) are loaded, THEN the cast info has already been loaded by
- *     the previous module so we just ignore it.
- *  3) Finally, if cast->type has not already been loaded, then we add that
- *     swig_cast_info to the linked list (because the cast->type) pointer will
- *     be correct.

-   Flags/methods for returning states.
-
-   The SWIG conversion methods, as ConvertPtr, return an integer
-   that tells if the conversion was successful or not. And if not,
-   an error code can be returned (see swigerrors.swg for the codes).
-
-   Use the following macros/flags to set or process the returning
-   states.
-
-   In old versions of SWIG, code such as the following was usually written:
-
-     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
-       // success code
-     } else {
-       //fail code
-     }
-
-   Now you can be more explicit:
-
-    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-    } else {
-      // fail code
-    }
-
-   which is the same really, but now you can also do
-
-    Type *ptr;
-    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
-    if (SWIG_IsOK(res)) {
-      // success code
-      if (SWIG_IsNewObj(res) {
-        ...
-	delete *ptr;
-      } else {
-        ...
-      }
-    } else {
-      // fail code
-    }
-
-   I.e., now SWIG_ConvertPtr can return new objects and you can
-   identify the case and take care of the deallocation. Of course that
-   also requires SWIG_ConvertPtr to return new result values, such as
-
-      int SWIG_ConvertPtr(obj, ptr,...) {
-        if (<obj is ok>) {
-          if (<need new object>) {
-            *ptr = <ptr to new allocated object>;
-            return SWIG_NEWOBJ;
-          } else {
-            *ptr = <ptr to old object>;
-            return SWIG_OLDOBJ;
-          }
-        } else {
-          return SWIG_BADOBJ;
-        }
-      }
-
-   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
-   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
-   SWIG errors code.
-
-   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
-   allows to return the 'cast rank', for example, if you have this
-
-       int food(double)
-       int fooi(int);
-
-   and you call
-
-      food(1)   // cast rank '1'  (1 -> 1.0)
-      fooi(1)   // cast rank '0'
-
-   just use the SWIG_AddCast()/SWIG_CheckState()

-/* -----------------------------------------------------------------------------
- * Type initialization:
- * This problem is tough by the requirement that no dynamic
- * memory is used. Also, since swig_type_info structures store pointers to
- * swig_cast_info structures and swig_cast_info structures store pointers back
- * to swig_type_info structures, we need some lookup code at initialization.
- * The idea is that swig generates all the structures that are needed.
- * The runtime then collects these partially filled structures.
- * The SWIG_InitializeModule function takes these initial arrays out of
- * swig_module, and does all the lookup, filling in the swig_module.types
- * array with the correct data and linking the correct swig_cast_info
- * structures together.
- *
- * The generated swig_type_info structures are assigned statically to an initial
- * array. We just loop through that array, and handle each type individually.
- * First we lookup if this type has been already loaded, and if so, use the
- * loaded structure instead of the generated one. Then we have to fill in the
- * cast linked list. The cast data is initially stored in something like a
- * two-dimensional array. Each row corresponds to a type (there are the same
- * number of rows as there are in the swig_type_initial array). Each entry in
- * a column is one of the swig_cast_info structures for that type.
- * The cast_initial array is actually an array of arrays, because each row has
- * a variable number of columns. So to actually build the cast linked list,
- * we find the array of casts associated with the type, and loop through it
- * adding the casts to the list. The one last trick we need to do is making
- * sure the type pointer in the swig_cast_info struct is correct.
- *
- * First off, we lookup the cast->type name to see if it is already loaded.
- * There are three cases to handle:
- *  1) If the cast->type has already been loaded AND the type we are adding
- *     casting info to has not been loaded (it is in this module), THEN we
- *     replace the cast->type pointer with the type pointer that has already
- *     been loaded.
- *  2) If BOTH types (the one we are adding casting info to, and the
- *     cast->type) are loaded, THEN the cast info has already been loaded by
- *     the previous module so we just ignore it.
- *  3) Finally, if cast->type has not already been loaded, then we add that
- *     swig_cast_info to the linked list (because the cast->type) pointer will
- *     be correct.
