-#   CC                          C Compiler path
-#   CXX                         C++ Compiler path

-#   PLATFORM_LIBS               Libraries flags
-#   PLATFORM_SHARED_EXT         Extension for shared libraries
-#   PLATFORM_SHARED_LDFLAGS     Flags for building shared library
-#                               This flag is embedded just before the name
-#                               of the shared library without intervening spaces
-#   PLATFORM_SHARED_CFLAGS      Flags for compiling objects for shared library
-#   PLATFORM_CCFLAGS            C compiler flags
-#   PLATFORM_CXXFLAGS           C++ compiler flags.  Will contain:
-#   PLATFORM_SHARED_VERSIONED   Set to 'true' if platform supports versioned
-#                               shared libraries, empty otherwise.
-#
-# The PLATFORM_CCFLAGS and PLATFORM_CXXFLAGS might include the following:
-#
-#       -DLEVELDB_CSTDATOMIC_PRESENT if <cstdatomic> is present
-#       -DLEVELDB_PLATFORM_POSIX     for Posix-based platforms
-#       -DSNAPPY                     if the Snappy library is present
