  8. # CMake support module for the DISTRHO Plugin Framework

  9. #

  10. # The purpose of this module is to help building music plugins easily, when the

  11. # project uses CMake as its build system.

  12. #

  13. # In order to use the helpers provided by this module, a plugin author should

  14. # add DPF as a subproject, making the function `dpf_add_plugin` available.

  15. # The usage of this function is documented below in greater detail.

  16. #

  17. # Example project `CMakeLists.txt`:

  18. #

  19. # ```

  20. # cmake_minimum_required(VERSION 3.7)

  21. # project(MyPlugin)

  22. #

  23. # add_subdirectory(DPF)

  24. #

  25. # dpf_add_plugin(MyPlugin

  26. #   TARGETS clap lv2 vst2 vst3

  27. #   UI_TYPE opengl

  28. #   FILES_DSP

  29. #       src/MyPlugin.cpp

  30. #   FILES_UI

  31. #       src/MyUI.cpp)

  32. #

  33. # target_include_directories(MyPlugin

  34. #   PUBLIC src)

  35. # ```

  36. #

  37. # Important: note that properties, such as include directories, definitions,

  38. # and linked libraries *must* be marked with `PUBLIC` so they take effect and

  39. # propagate into all the plugin targets.

  48. # ------------------------------------------------------------------------------

  49. #

  50. # Add a plugin built using the DISTRHO Plugin Framework.

  52. # ------------------------------------------------------------------------------

  53. # Created targets:

  54. #

  55. #   `<name>`

  56. #       static library: the common part of the plugin

  57. #       The public properties set on this target apply to both DSP and UI.

  58. #

  59. #   `<name>-dsp`

  60. #       static library: the DSP part of the plugin

  61. #       The public properties set on this target apply to the DSP only.

  62. #

  63. #   `<name>-ui`

  64. #       static library: the UI part of the plugin

  65. #       The public properties set on this target apply to the UI only.

  66. #

  67. #   `<name>-<target>` for each target specified with the `TARGETS` argument.

  76. #

  77. #   `UI_TYPE` <type>

  94. #   `FILES_UI` <file1>...<fileN>

  95. #       list of sources which are part of the UI

  96. #       empty indicates the plugin does not have UI
