shared dependencies for Synthizer and its components
This submodule contains a CMakeLists.txt which builds everything that needs building, and uses CMake FetchContent to allow itself to be used in either Synthizer or Synthcore by ensuring that it only builds once.
We could fetch these individually if we wanted, but it is helpful to IDEs to have them available, and when used as a submodule we avoid fetching every time someone has to regenerate the CMake scripts. Plus, this setup makes them easily vendored, and thus allows builds which don't require network access.
Specifically, the CMakeLists.txt at the root of this project does:
FetchContent_declare(...)
parent repositories are responsible for the FetchContent_MakeAvailable calls, in order to only include what they use
when they need it.
For WDL's objlib target (wdl_objlib):
target_include_directories(test PRIVATE $<TARGET_PROPERTY:wdl_objlib,INTERFACE_INCLUDE_DIRECTORIES>)
Is required because CMake will not propagate this value itself.
In many cases, we add our own CMakeLists.txt file to the deps/third_party folder to e.g. provide an interface target.
The third-party dependencies are as follows. None require binary attribution, and all are available as
FetchContent_MakeAvailable after an add_subdirectory to this repo:
- Benchmark is google/benchmark.
- boost_partial is a header-only subset of Boost extracted with BCP.
- catch2 is a C++ testing framework.
- concurrentqueue is what it sounds like it is.
- cpp-11-on-multicore is a set of utilities from here for, e.g., semaphores.
- dr_libs are a set of audio-related libraries, primarily decoders for MP3, Wav, and Flac.
- hedley is a library for abstracting over C++ compiler differences.
- Miniaudio is a library for audio device I/O.
- pdqsort is pattern-defeating quicksort, an unstable sorting algorithm that requires no additional memory.
- WDL is an SDK from Cockos, the authors of Reaper, with various DSP-related utilities.
You probably need:
set(BENCHMARK_ENABLE_TESTING OFF)
At the top of your CMakeLists.txt. This has to be done globally and disables Benchmark's test building, which wants gtest.
Catch2 provides a CMake integration, which requires an additional CMake include directory. Use:
list(APPEND CMAKE_MODULE_PATH ${catch2_SOURCE_DIR}/extras)
INCLUDE(Catch)
To enable it.
For WDL's objlib target (wdl_objlib):
target_include_directories(test PRIVATE $<TARGET_PROPERTY:wdl_objlib,INTERFACE_INCLUDE_DIRECTORIES>)
Is required because CMake will not propagate this value itself.
Same for:
target_compile_definitions(mytarget WDL_RESAMPLE_TYPE=float)
