ramsesgpu's Issues

cmake error upon generate

Cmake reports an error after configuring, during generate stage, but afterward the project builds fine:

-- Configuring done
CMake Error at src/CMakeLists.txt:25 (add_executable):
  Cannot find source file:

    gpu_macros.cpp

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx


-- Generating done
-- Build files have been written to: /home/pkestene/etudes/GPU/Hydro/git/github/ramsesGPU/build_cmake_cpu

The problem could be related to cmake issue:
https://gitlab.kitware.com/cmake/cmake/issues/17462
To be investigated.

Autotools broken

Autotools (top-level autoconf.ac and m4 macros) need to be refreshed to build again.
Let's fix that.

Develop alternative build system using cmake

Currently the system uses autotools; it's more than 10 years old.
It relies on some dirty tricks to handle cpp file as if they were cuda, in order to able either a cpu or gpu build.

Several issues makes the code difficult to build on most current linux platform.

Let's try to replace autotools with cmake.
