* Update the build system to support intermediate installs (instead of
exposing CMake targets that were only usable from within the main
CMakeLists.txt).
* Finish the emscripten build and add detailed instructions in
README.md.
* Get rid of runtime GLSL files by embedding them into a C file. This
solves the annoying problem of where to install them and how to find
them at runtime.
* Provide FindAzur.cmake to access the library. At the moment the module
still needs to be found which requires a set(CMAKE_MODULE_PATH) in
user applications. I consider this an acceptable compromise.
* Automatically go soft-fullscreen in the emscripten application.
