Question about install C++ API

[HAODONG YAN]

I install torch_scatter via pip. And in which path should I conduct your code
`mkdir build
cd build

Add -DWITH_CUDA=on support for CUDA support

cmake -DCMAKE_PREFIX_PATH="..." ..
make
make install`

should I download your source code? I am sorry I am not familiar with C++

[Matthias Fey]

This is only relevant for the C++ API. Since you are using Python, pip install is sufficient.

Hi, but I need to install C++ API cuz I script my own model via torch.jit.script. When I using it in c++ I got the error like #147

[HAODONG YAN]

I followed your tutorial and when I ran "make" command, I got error as follows:
make:*** No targets specified and no makefile found. Stop.
My platform is win10

Then I am trying to ran cmake -G “Unix Makefiles” … to generate makefiles, But I got error as follows:
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.
