Features: Add COMPILE_FEATURES generator expression. Allow setting build properties based on the features available for a target. The availability of features is determined at generate-time by evaluating the link implementation. Ensure that the <LANG>_STANDARD determined while evaluating COMPILE_FEATURES in the link implementation is not lower than that provided by the INTERFACE of the link implementation. This is similar to handling of transitive properties such as POSITION_INDEPENDENT_CODE. 2014-05-15 11:32:30 +02:00

Features: Properly evaluate if the compiler supports cxx_final. Previously we expanded HAVE_FINAL to determine what the copied_file number would be, but when we don't have cxx_final than HAVE_FINAL is not defined. What we really want is to use expected_result. 2014-12-31 10:25:33 -05:00			`add_custom_command(OUTPUT "${CMAKE_CURRENT_BINARY_DIR}/copied_file${expected_result}.cpp"`

Tests: Revert workaround for COMPILE_FEATURES genex bug The second hunk of commit 07d1f6fc (Features: Properly evaluate if the compiler supports cxx_final, 2014-12-31) was a workaround for a bug in the COMPILE_FEATURES generator expression that caused it never to return 0. Revert the workaround so we can fix the bug instead. 2015-01-14 13:41:45 -05:00			`add_library(empty "${CMAKE_CURRENT_BINARY_DIR}/copied_file${genexvar}.cpp")`
