# requires:
# - INCLUDE_DIRS: directories searched for includes (/I)
# - INCLUDE_CFLAGS: specific compilation flags (C)
# - INCLUDE_CXXFLAGS: specific compilation flags (C++)
# - INCLUDE_LDFLAGS: library flags like like link location (/L)
# - INCLUDE_LIBS: additional libraries to link against (e.g. advapi32.dll)
# provides:
# - generic implicit rules for compilation/linking
#

# TODO: which flags to enable?
# /nologo: disable MS disclaimer
# /EHsc: enable C++ exception handling
# /Ox: optimize what you can
# /Zi: enable debug information
# /MD: multithreaded runtime
# /W <n>: show warnings (level 1 to 4)
# /Wp64: warn about possible 64-bit issues
# using /W2 for now, /W3 shows lots of problems
# in boost/asio/openssl (size_t -> int conversion)
# /Wp64 breaks Qt and SSL
# /Wall: enable all warnings (produces tons of warnings!)
# /WX: treat warnings as errors
