From 9b023a56a3dd42c96a95e1d56698d68e286d9abd Mon Sep 17 00:00:00 2001 From: lat9nq <22451773+lat9nq@users.noreply.github.com> Date: Mon, 14 Dec 2020 18:06:24 -0500 Subject: [PATCH] cmake/conan: Conditionally add target Boost::context Addresses an issue with the two competing versions of Conan's Boost package that are currently floating around. Adds the Boost::context target only if it's recognized by CMake as a target. --- CMakeLists.txt | 23 +++++++++++++++++------ 1 file changed, 17 insertions(+), 6 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 2366d372c..66bbd985a 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -194,13 +194,18 @@ macro(yuzu_find_packages) unset(FN_FORCE_REQUIRED) endmacro() -if (NOT Boost_FOUND) - find_package(Boost 1.73.0 COMPONENTS context headers QUIET) - if (Boost_FOUND) - set(Boost_LIBRARIES Boost::boost Boost::context) +find_package(Boost 1.73.0 COMPONENTS context headers QUIET) +if (Boost_FOUND) + set(Boost_LIBRARIES Boost::boost) + # Conditionally add Boost::context only if the active version of the Conan or system Boost package provides it + # The old version is missing Boost::context, so we want to avoid adding in that case + # The new version requires adding Boost::context to prevent linking issues + # + # This one is used by Conan on subsequent CMake configures, not the first configure. + if (TARGET Boost::context) + list(APPEND Boost_LIBRARIES Boost::context) endif() -endif() -if (NOT Boost_FOUND) +else() message(STATUS "Boost 1.73.0 or newer not found, falling back to Conan") list(APPEND CONAN_REQUIRED_LIBS "boost/1.73.0") endif() @@ -312,6 +317,12 @@ if (CONAN_REQUIRED_LIBS) if (NOT Boost_FOUND) find_package(Boost 1.73.0 REQUIRED COMPONENTS context headers) set(Boost_LIBRARIES Boost::boost) + # Conditionally add Boost::context only if the active version of the Conan Boost package provides it + # The old version is missing Boost::context, so we want to avoid adding in that case + # The new version requires adding Boost::context to prevent linking issues + if (TARGET Boost::context) + list(APPEND Boost_LIBRARIES Boost::context) + endif() endif() # Due to issues with variable scopes in functions, we need to also find_package(qt5) outside of the function
