0001 # Module that tries to find the Kipi library
0002 #
0003 # Input values :
0004 #
0005 # KIPI_LOCAL_DIR    - If you have put a local version of libkipi into your source tree,
0006 #                     set this variable to the relative path from the local directory.
0007 #
0008 # Output values :
0009 #
0010 #  KIPI_FOUND       - System has libkipi
0011 #  KIPI_INCLUDE_DIR - The libkipi include directory
0012 #  KIPI_LIBRARIES   - Link these to use libkipi
0013 #  KIPI_DEFINITIONS - Compiler switches required for using libkipi
0014 #  KIPI_VERSION     - The release version of the Kipi library
0015 #  KIPI_SO_VERSION  - The binary SO version of the Kipi library
