From 17689af9065bf2f70e4c0b7b5ad16553223b665d Mon Sep 17 00:00:00 2001 From: King_DuckZ Date: Wed, 10 Aug 2016 01:30:28 +0200 Subject: [PATCH] Conditionally build the Qt5 gui project. Take the chance to introduce cmake_dependent_option. Using it for some of the old options as well. --- CMakeLists.txt | 38 ++++++--- cmake/Modules/TargetArch.cmake | 152 +++++++++++++++++++++++++++++++++ 2 files changed, 178 insertions(+), 12 deletions(-) create mode 100644 cmake/Modules/TargetArch.cmake diff --git a/CMakeLists.txt b/CMakeLists.txt index 4c11b52..8899275 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -31,18 +31,34 @@ include(CPack) include(CTest) include(timestamp) include(shared_git_project) +include(TargetArch) +include(CMakeDependentOption) -option(DINDEXER_DEBUG_CFG_FILE "Enable to set the config file path to the build path" OFF) -option(DINDEXER_WITH_MEDIA_AUTODETECT "Enable code that tries to autodetect the media type and sets --type automatically" ON) -option(DINDEXER_NATIVE_RELEASE "Pass the -march=native flag to the compiler for release builds" OFF) -if (CMAKE_COMPILER_IS_GNUCXX AND CMAKE_CXX_COMPILER_VERSION_MAJOR EQUAL "5") -
