RESOURCE

Specify resource files in a FRAMEWORK or BUNDLE.

Target marked with the FRAMEWORK or BUNDLE property generate framework or application bundle (both OS X and iOS is supported) or normal shared libraries on other platforms. This property may be set to a list of files to be placed in the corresponding directory (eg. Resources directory for OS X) inside the bundle. On non-Apple platforms these files may be installed using the RESOURCE option to the install(TARGETS) command.

Following example of Application Bundle:

add_executable(ExecutableTarget
  addDemo.c
  resourcefile.txt
  appresourcedir/appres.txt
)

target_link_libraries(ExecutableTarget heymath mul)

set(RESOURCE_FILES
  resourcefile.txt
  appresourcedir/appres.txt
)

set_target_properties(ExecutableTarget PROPERTIES
  MACOSX_BUNDLE TRUE
  MACOSX_FRAMEWORK_IDENTIFIER org.cmake.ExecutableTarget
  RESOURCE "${RESOURCE_FILES}"
)

will produce flat structure for iOS systems:

ExecutableTarget.app
  appres.txt
  ExecutableTarget
  Info.plist
  resourcefile.txt

For OS X systems it will produce following directory structure:

ExecutableTarget.app/
  Contents
    Info.plist
    MacOS
      ExecutableTarget
    Resources
      appres.txt
      resourcefile.txt

For Linux, such cmake script produce following files:

ExecutableTarget
Resources
  appres.txt
  resourcefile.txt
