# CMake module to search for Sqlite3 library
#
# If it's found it sets SQLITE3_FOUND to TRUE
# and following variables are set:
#    SQLITE3_INCLUDE_DIR
#    SQLITE3_LIBRARY


# Normally there is no need to specify /usr/... paths because 
# cmake will look there automatically. However the NO_DEFAULT_PATH
# prevents this behaviour allowing you to use no standard file
# locations in preference over standard ones. Note in this case
# you then need to explicitly add /usr and /usr/local prefixes
# to the search list. This applies both to FIND_PATH and FIND_LIBRARY
