From a976c2e3ba146df2fda9293c6fce9e11d96ac038 Mon Sep 17 00:00:00 2001 From: James Rowe Date: Thu, 30 Jun 2016 11:59:32 -0600 Subject: CMake: Fix for QT 5.7 overwriting -std=c++1y flag In QT 5.7 they added a new check for CXX features which appends a minimum required standard to the CXX_FLAGS. Because we were writing the flag directly previously, cmake assumed it needed to add a c++11 flag to the build. This tells cmake to use c++14 on every build. --- CMakeLists.txt | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) (limited to 'CMakeLists.txt') diff --git a/CMakeLists.txt b/CMakeLists.txt index 779eb8e50..4a271c36f 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -1,6 +1,5 @@ -# CMake 3.1 required for Qt5 settings to be applied automatically on -# dependent libraries and IMPORTED targets. -cmake_minimum_required(VERSION 3.1) +# CMake 3.2 required for cmake to know the right flags for CXX standard on OSX +cmake_minimum_required(VERSION 3.2) function(download_bundled_external remote_path lib_name prefix_var) set(prefix "${CMAKE_BINARY_DIR}/externals/${lib_name}") @@ -63,8 +62,11 @@ if (NOT DEFINED ARCHITECTURE) endif() message(STATUS "Target architecture: ${ARCHITECTURE}") +set(CMAKE_CXX_STANDARD 14) +set(CMAKE_CXX_STANDARD_REQUIRED ON) + if (NOT MSVC) - set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++1y -Wno-attributes") + set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-attributes") set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS}") else() # Silence "deprecation" warnings -- cgit v1.2.3
