# Dependency checking
#
# TODO: Use find_library for other stuff?
#
# NOTES:
# there are numerous possible cases:
# - dependency may be required or optional
# - dependency may be already installed (but optionally the bundled one may be used)
#
# TODO: We should have a number of options for optional dependencies (disable, force bundled, bundled or native, force native)
# e.g. the OpenGL plugin defaults to force native, so we error out if no GL libs are found. The user is free to explicitely disable it though.
# Stuff which is likely to be needed by users is made an option with default ON, other stuff (like e.g. sound backends) is made completely optionally.
# TODO: wxWidgets: Since _DEBUG gets defined in Debug builds, wxWidgets will enable some debugging functionality as well.
# However, because we still link against release wx libs, which makes compilation fail because of undefined references.
# When building the Debug configuration, we should probably check if the debug wx libs are available and fall back to the bundled ones otherwise.

# Process externals and setup their include directories

# NOTES about adding Externals:
# - add the include directory here
# - make sure to tell cmake to link them statically or dynamically (most should be linked statically)
# - ideally, the nested CMakeLists.txt should only contain a list of sources and an add_library()+target_link_libraries() call pair
# - place the CMakeLists.txt in the first-level subdirectory, e.g. Externals/WiiUse/CMakeLists.txt (that is: NOT in some Src/ subdirectory)
