#   SRC one or more directory roots to scan for C/C++ files.
#   CFLAGS the compiler flags to be used, used both for C and C++.
#   CXXFLAGS the compiler flags to be used for c++, if set overrides CFLAGS.
#   LDFLAGS the linker flags to be used, used both for C and C++.

#   VERSIONINFO_RESOURCE Input file for RC. Setting this implies that RC will be run
#   RCFLAGS flags for RC.
#   EMBED_MANIFEST if true, embed manifest on Windows.
#   MAPFILE mapfile
#   USE_MAPFILE_FOR_SYMBOLS if true and this is a STATIC_BUILD, just copy the
#       mapfile for the output symbols file
#   CC the compiler to use, default is $(CC)
