Picasso is simply a software renderer in order to play around with simulating OpenGL, doing ray-tracing, multi-threading, etc.
Remember to bring in the submodules (this should bring in imgui)
git submodule update
For now, I'm trying CMake (cannot say I'm thrilled). Remember to do an out-of-source build
mkdir build
cd build
cmake ..
cmake --build .
So that CMake doesn't polute your main directory with garbage.
To clean should be an easy rm -rf build
Installing is easy (if you have a package manager). If not installing SDL2 is on you.
sudo apt-get install libsdl2-dev
Windows needs a little more help finding the SDL2 libraries.
How the build system is setup now is that it will look for the SDL2 env
variable that should have the path to the base directory of the extracted
SDL2 development libraries.
What I did is to create a .set_env.bat that the only thing it does is
set that environment variable.
Of course, as that path is only relevant to me, I didn't check in that file.
I have a very simple .ycm_extra_conf.py file installed.
The only thing it needs to work out of the box (hopefully) is that we need the
env variable SDL2 to point to the include path of SDL2.
