0001 # This module provides the macro TEST_FIND_PACKAGE()
0002 #
0003 # TEST_FIND_PACKAGE(package prefix var1 .. varN )
0004 #    It can be used to test a CMake Find-module.
0005 #    It executes FIND_PACKAGE(<package>) and then prints some results.
0006 #    <package> is the same as for FIND_PACKAGE() and
0007 #    prefix should be the prefix which is used in that module for
0008 #    all variables.
0009 #    It checks <prefix>_FOUND to decide whether the module was successful or not.
0010 #
0011 # Example:
0012 #   test_find_package(Xine  XINE  VERSION INCLUDE_DIR LIBRARY)
0013 #
0014 # This will check XINE_FOUND and then print the variables XINE_VERSION, XINE_INCLUDE_DIR and XINE_LIBRARY.
