Let CMakeLists.txt export ALURE_LIBRARIES and ALURE_INCLUDE_DIRS

[karamellpelle]

Hello! Is it possible to let ./CMakeLists.txt export ALURE_LIBRARIES and ALURE_INCLUDE_DIRS? I have alure as a git submodule and use it as a cmake submodule (add_subdirectory( alure )). In my top CMakeLists.txt it would be nice to use these variables and not hardcode the paths and link libraries by hand.

For example, the submodule glfw of mine makes this possible:

set(GLFW_LIBRARIES ${glfw_LIBRARIES} CACHE STRING "Dependencies of GLFW")

I suppose this at the end will do the job:

set(ALURE_LIBRARIES alure2 ${alure_libs} CACHE STRING "Dependencies of ALURE")

But better: Add all include and link dependencies of target alure2 with target_include_directories() and target_link_libraries(). And for each optional package dependency found (like mpg123), add it to alure2. Now I have to find these optional packages (i.e. mpg123) by myself again, and then add them to my target.

This should be the case now. It should also work for alure2_s (for static linking). Is there anything else it should do to "expose" the alure2 and alure2_s targets for whatever includes this CMakeLists.txt?

I'm not sure what else the CMakeLists.txt should do; I'm not very into CMake right now.

However, using Alure with the newest commit as a submodule works well. Thank you!
