# - Convenience macros for printing properties and variables, useful e.g. for debugging.
#
#
# CMAKE_PRINT_PROPERTIES([TARGETS target1 .. targetN]
#                        [SOURCES source1 .. sourceN]
#                        [DIRECTORIES dir1 .. dirN]
#                        [TESTS test1 .. testN]
#                        [CACHE_ENTRIES entry1 .. entryN]
#                        PROPERTIES prop1 .. propN )
#
# This macro prints the values of the properties of the given targets,
# source files, directories, tests or cache entries. Exactly one of the
# scope keywords must be used.
# Example:
#   cmake_print_properties(TARGETS foo bar PROPERTIES LOCATION INTERFACE_INCLUDE_DIRS)
# This will print the LOCATION and INTERFACE_INCLUDE_DIRS properties for both
# targets foo and bar.
#
#
# CMAKE_PRINT_VARIABLES(var1 var2 .. varN)
#
# This macro will print the name of each variable followed by its value.
# Example:
#   cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION THIS_ONE_DOES_NOT_EXIST)
# Gives:
#   -- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; THIS_ONE_DOES_NOT_EXIST=""
