Nothing gets build from cmake

[Bram Stolk]

I clone the repository recursively, as suggested by the documentation:

$ git clone --recursive https://github.com/mitsuba-renderer/enoki
Cloning into 'enoki'...
...
Cloning into '/home/bram/src/enoki/ext/cub'...
...
Cloning into '/home/bram/src/enoki/ext/pybind11'...
...
Cloning into '/home/bram/src/enoki/ext/pybind11/tools/clang'...
...

I then call cmake

$ cd enoki
$ mkdir build
$ cd build
$ CXX=clang++-8 CC=clang-8 cmake ../
-- The CXX compiler identification is Clang 8.0.0
-- Check for working CXX compiler: /usr/bin/clang++-8
-- Check for working CXX compiler: /usr/bin/clang++-8 -- works

-- Enoki: using libc++.
-- Found Sphinx: /usr/bin/sphinx-build  
-- Configuring done
-- Generating done
-- Build files have been written to: /home/bram/src/enoki/build

When I then try to make, nothing gets built.

$ make
$

I expect at least the tests to get built with that.

This is on Ubuntu 18.04.4 LTS

You need to run ccmake or cmake-gui to turn on the flags that you need. (CUDA, Autodiff, python bindings, tests, etc.). By default it is just a header file library. Note that the tests are extremely heavy to compile.
