Building

Polypropylene is a pure CMake project. It does not depend on any third-party software. Building follows the straightforward CMake workflow. When you are in the project's root directory, run the following commands to build:

mkdir build
cd build
cmake ..
make

Options

Building Polypropylene can be customised. The following CMake options configure Polypropylene's build. By default, all options are activated, i.e., set to ON.

• POLYPROPYLENE_WITH_JSON: Includes the nlohmann::json library for loading and writing EntityPrefabs from and to json files.
• POLYPROPYLENE_WITH_EXAMPLES: Specifies if examples should be built or not.

Linking

Polypropylene is built as a static library. To link your project against Polyproplene, you need to:

• Add Polypropylene's include/ directory to your includes. In CMake this can be done with include_directories(path/to/Polypropylene/include).
• Link your library against polypropylene.a / polypropylene.lib, depending on your compiler. In CMake this can be done with target_link_libraries(yourprogramtarget polypropylene).

We do not provide any find scripts so far. Choose the way that works best for you to locate Polypropylene in your file system. For example, Polypropylene can directly be included into your project's CMakeLists.txt (add_subdirectory(Polypropylene)) by using symlinks or git submodules.
