# MYSQL_STORAGE_ENGINE Macro creates a project to build storage engine
# library. 
#
# Parameters:
# engine - storage engine name.
# variable ENGINE_BUILD_TYPE should be set to "STATIC" or "DYNAMIC"
# Remarks:
# ${engine}_SOURCES  variable containing source files to produce the library must set before
# calling this macro
# ${engine}_LIBS variable containing extra libraries to link with may be set
