From d49f1c5e9400c6b5d6dc205b4dadad2fa21f6eb0 Mon Sep 17 00:00:00 2001 From: Stephen Kelly Date: Wed, 19 Nov 2014 00:30:40 +0100 Subject: [PATCH] Build CMake with most-recent available language dialect. When CMake is built with CMake 3.1 or later, appropriate -std= options will be added for GNU and Clang compilers while building C and CXX code. This allows taking advantage of 'hidden' language features such as move-constructors, and allows the standard library to enable the use of more-advanced features too, where available. This does not change CMake host compiler requirements. --- CMakeLists.txt | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/CMakeLists.txt b/CMakeLists.txt index 58e0a1f22..90fc1a2e7 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -36,6 +36,10 @@ if("${CMake_SOURCE_DIR}" STREQUAL "${CMAKE_SOURCE_DIR}") endmacro() endif() +# Use most-recent available language dialects with GNU and Clang +set(CMAKE_C_STANDARD 11) +set(CMAKE_CXX_STANDARD 14) + # option to set the internal encoding of CMake to UTF-8 option(CMAKE_ENCODING_UTF8 "Use UTF-8 encoding internally (experimental)."
