> Does anybody actually use "find_package(midas)", does it actually work for anybody?

What we do is to include midas as a submodule and than we call find_package:

    add_subdirectory(midas)
    list(APPEND CMAKE_PREFIX_PATH ${CMAKE_CURRENT_SOURCE_DIR}/midas)
    find_package(Midas REQUIRED)

For us it works fine like this but we kind of always compile Midas fresh and don't use a version on our system (keeping the newest version). 

Without the find_package the build does not work for us.
