# - Find LiteSQL
#
# Find the LiteSQL library, and defines a function to generate C++ files
# from the database xml file using litesql-gen fro
#
# This module defines the following variables:
#   LITESQL_FOUND  -  True if library and include directory are found
# If set to TRUE, the following are also defined:
#   LITESQL_INCLUDE_DIRS  -  The directory where to find the header file
#   LITESQL_LIBRARIES  -  Where to find the library file
#   LITESQL_GENERATE_CPP - A function, to be used like this:
# LITESQL_GENERATE_CPP("db/database.xml"  # The file defining the db schemas
#                      "database"         # The name of the C++ “module”
#                                         # that will be generated
#                       LITESQL_GENERATED_SOURCES # Variable containing the
#                                                 resulting C++ files to compile
#
# For conveniance, these variables are also set. They have the same values
# than the variables above.  The user can thus choose his/her prefered way
# to write them.
