From e6757089b465a041ea1a96252359f31afc2e323e Mon Sep 17 00:00:00 2001 From: Rafael Kitover Date: Mon, 19 Dec 2016 13:16:07 -0800 Subject: [PATCH] packaging support improvements This grew out of my work creating an sfml port for macports, but should be helpful for package maintainers of various distributions: * add an SFML_USE_SYSTEM_DEPS option to ignore everything in extlibs/ except for headers/stb_image, and use the system versions * install pkg-config files if a pkg-config program is found and either lib/pkgconfig or libdata/pkgconfig exists under the INSTALL_PREFIX, or the SFML_INSTALL_PKGCONFIG_FILES flag is set explicitly * install pkg-config files for static libs too, add the necessary Requires.private and Libs.private entries to the .pc files to support static linking * on OS X, honor all INSTALL_NAME and RPATH related cmake variables and only set the INSTALL_NAME_DIR to "@rpath" if none of them is set, this preserves the default behavior of using @rpath but also allows overriding by the usual cmake mechanisms --- CMakeLists.txt | 73 ++++++++++++++++++++++++------------ cmake/Config.cmake | 13 +++++++ cmake/Macros.cmake | 14 +++++-- tools/pkg-config/sfml-audio.pc.in | 3 ++ tools/pkg-config/sfml-graphics.pc.in | 3 ++ tools/pkg-config/sfml-window.pc.in | 2 + 6 files changed, 81 insertions(+), 27 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index e7914ac..419d56d 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -16,6 +16,9 @@ sfml_set_option(CMAKE_BUILD_TYPE Release STRING "Choose the type of build (Debug # Suppress Cygwin legacy warning set(CMAKE_LEGACY_CYGWIN_WIN32 0) +# Suppress Mac OS X RPATH warnings and adopt new related behaviors +cmake_policy(SET CMP0042 NEW) + # set Android specific options # define the minimum API level to be used @@ -130,6 +133,39 @@ if(NOT BUILD_SHARED_LIBS) add_definitions(-DSFML_STATIC) endif() +# allow not using bundled dependencies with a switch +# (except for stb_image) +# yes this is horrible, but GLOB_RECURSE sucks +sfml_set_option(SFML_USE_SYSTEM_DEPS FALSE BOOL "TRUE to use system dependencies, FALSE to use the bundled ones.") +if(SFML_USE_SYSTEM_DEPS) + if(SFML_INSTALL_XCODE_TEMPLATES) + message(FATAL_ERROR "XCode templates installation cannot be used with the SFML_USE_SYSTEM_DEPS option (the bundled frameworks are required.)") + endif() + + file(GLOB_RECURSE DEP_LIBS "${CMAKE_SOURCE_DIR}/extlibs/libs*/*") + file(GLOB_RECURSE DEP_BINS "${CMAKE_SOURCE_DIR}/extlibs/bin*/*") + file(GLOB_RECURSE DEP_HEADERS "${CMAKE_SOURCE_DIR}/extlibs/headers/*") + + foreach(DEP_FILE ${DEP_LIBS} ${DEP_BINS} ${DEP_HEADERS}) + get_filename_component(DEP_DIR ${DEP_FILE} PATH) + + if(NOT DEP_DIR MATCHES "/stb_image(/|$)") + set(CMAKE_IGNORE_PATH ${CMAKE_IGNORE_PATH} ${DEP_DIR}) + endif() + + get_filename_component(DEP_PARENT_DIR ${DEP_DIR} PATH) + while(NOT DEP_PARENT_DIR STREQUAL "${CMAKE_SOURCE_DIR}/extlibs") + if(NOT DEP_DIR MATCHES "/stb_image(/|$)") + set(CMAKE_IGNORE_PATH ${CMAKE_IGNORE_PATH} ${DEP_PARENT_DIR}) + endif() + + get_filename_component(DEP_PARENT_DIR ${DEP_PARENT_DIR} PATH) + endwhile() + endforeach() + + list(REMOVE_DUPLICATES CMAKE_IGNORE_PATH) +endif() + # Visual C++: remove warnings regarding SL security and algorithms on pointers if(SFML_COMPILER_MSVC) # add an option to choose whether PDB debug symbols should be generated (defaults to true when possible) @@ -202,30 +238,6 @@ if(SFML_OS_MACOSX) set(XCODE_TEMPLATES_ARCH "\$(NATIVE_ARCH_ACTUAL)") endif() -if(SFML_OS_LINUX OR SFML_OS_FREEBSD) -
