CMakePrintHelpers
-----------------
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 DOES_NOT_EXIST)
Gives::
-- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; DOES_NOT_EXIST=""
