*	Features: Extract strings from test binary more reliably (#15736)	Brad King	2015-09-10	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	Since commit v3.1.0-rc1~635^2~7 (project: Add infrastructure for recording CXX compiler features, 2013-10-17) we compile a test source to a binary and then extract "<LANG>_FEATURES:..." strings from the binary with the file(STRINGS) command. Add a newline at the beginning of the string literal to be sure file(STRINGS) can extract the first entry as a string independent of whatever else the compiler may put before the storage it allocates for the literal within the binary.
*	Features: Use the features symbol in the feature-test compile.	Stephen Kelly	2014-05-15	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	Clang discards the entire string if it is not used, removing the ability to read the features from the compiled binary. That is prevented by using the symbol. GNU with -O3 also discards the string, so use the string in a way which is determined by a runtime value (argc) to prevent it being discarded.
*	Project: Use nullary form of main for compile feature tests.	Stephen Kelly	2014-05-07	1	-1/+1

*	Features: Make CMAKE_CXX_KNOWN_FEATURES a property.	Stephen Kelly	2014-05-02	1	-1/+4
\| \| \| \| \|	As a 'built-in' variable it imposes a cost on all variable lookups and it is expected to be rarely used.
*	project: Add infrastructure for recording CXX compiler features	Stephen Kelly	2014-04-07	1	-0/+57
	Add a feature test using the compiler macros and the preprocessor to determine available features. Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable containing all features known to CMake. Add language standard specific variables for internal use to determine the standard-specific compile flags to use. This will be extended to other languages in the future. Follow-up commits will add features which will be recorded by the feature test.
