From ea78f9a2ef89918e758c3a52eea5d581a944b42f Mon Sep 17 00:00:00 2001 From: lat9nq <22451773+lat9nq@users.noreply.github.com> Date: Wed, 21 Apr 2021 02:57:22 -0400 Subject: [PATCH] cmake: Allow FFmpeg external usage and cleanup Sets find_package(FFmpeg) to QUIET instead of REQUIRED. This allows using the FFmpeg external in cases where there is no suitable installed version of FFmpeg. Also fixes a bug where multiple CMake configures causes FFmpeg_LIBRARIES to concatenate on itself, producing cyclical dependencies. Unsets the variable before building it in the foreach loop. Fixes FFmpeg_INCLUDE_DIR not including the headers generated at run time. --- CMakeLists.txt | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 2c1c3d560..2cddf2ad9 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -19,7 +19,7 @@ CMAKE_DEPENDENT_OPTION(YUZU_USE_BUNDLED_QT "Download bundled Qt binaries" ON "EN option(ENABLE_WEB_SERVICE "Enable web services (telemetry, etc.)" ON) -CMAKE_DEPENDENT_OPTION(YUZU_USE_BUNDLED_FFMPEG "Download/Build bundled yuzu" ON "WIN32" OFF) +CMAKE_DEPENDENT_OPTION(YUZU_USE_BUNDLED_FFMPEG "Download/Build bundled FFmpeg" ON "WIN32" OFF) option(YUZU_USE_QT_WEB_ENGINE "Use QtWebEngine for web applet implementation" OFF) @@ -394,7 +394,7 @@ set(FFmpeg_COMPONENTS if (NOT YUZU_USE_BUNDLED_FFMPEG) # Use system installed FFmpeg - find_package(FFmpeg REQUIRED COMPONENTS ${FFmpeg_COMPONENTS}) + find_package(FFmpeg QUIET COMPONENTS ${FFmpeg_COMPONENTS}) if (FFmpeg_FOUND) # Overwrite aggregate defines from FFmpeg module to avoid over-linking libraries. @@ -433,6 +433,7 @@ if (YUZU_USE_BUNDLED_FFMPEG) set(FFmpeg_FOUND YES) endif() + unset(FFmpeg_LIBRARIES CACHE) foreach(COMPONENT ${FFmpeg_COMPONENTS}) set(FFmpeg_${COMPONENT}_PREFIX "${FFmpeg_BUILD_DIR}/lib${COMPONENT}") set(FFmpeg_${COMPONENT}_LIB_NAME "lib${COMPONENT}.a") @@ -445,7 +446,7 @@ if (YUZU_USE_BUNDLED_FFMPEG) endforeach() set(FFmpeg_INCLUDE_DIR - ${FFmpeg_PREFIX} + "${FFmpeg_PREFIX};${FFmpeg_BUILD_DIR}" CACHE PATH "Path to FFmpeg headers" FORCE) # `configure` parameters builds only exactly what yuzu needs from FFmpeg @@ -492,13 +493,11 @@ if (YUZU_USE_BUNDLED_FFMPEG) # ALL makes this custom target build every time # but it won't actually build if the DEPENDS parameter is up to date - add_custom_target(ffmpeg-build ALL DEPENDS ${FFmpeg_LIBRARIES}) add_custom_target(ffmpeg-configure ALL DEPENDS ${FFmpeg_MAKEFILE}) + add_custom_target(ffmpeg-build ALL DEPENDS ${FFmpeg_LIBRARIES} ffmpeg-configure) if (FFmpeg_FOUND) message(STATUS "Found FFmpeg version ${FFmpeg_VERSION}") - - add_dependencies(ffmpeg-build ffmpeg-configure) else() message(FATAL_ERROR "FFmpeg not found") endif()
