From 2c0d5d01ee8b129116acec2fb359e7e6514876cb Mon Sep 17 00:00:00 2001 From: Raul Tambre Date: Mon, 14 Sep 2020 14:27:56 +0300 Subject: CUDA: Support scattered installations when crosscompiling with Clang Previously when CMAKE_CROSSCOMPILING was ON we'd end up not setting the target directory if the non-scattered one didn't exist. Fix this by assuming a scattered installation if the target directory isn't set after the crosscompiling logic. --- Help/release/dev/cuda-clang-scattered-cross.rst | 5 +++++ Modules/CMakeDetermineCUDACompiler.cmake | 7 +++++-- 2 files changed, 10 insertions(+), 2 deletions(-) create mode 100644 Help/release/dev/cuda-clang-scattered-cross.rst diff --git a/Help/release/dev/cuda-clang-scattered-cross.rst b/Help/release/dev/cuda-clang-scattered-cross.rst new file mode 100644 index 0000000..7278dcb --- /dev/null +++ b/Help/release/dev/cuda-clang-scattered-cross.rst @@ -0,0 +1,5 @@ +cuda-clang-scattered-cross +-------------------------- + +* Scattered toolkit installations are now recognized when crosscompiling + ``CUDA`` using Clang. diff --git a/Modules/CMakeDetermineCUDACompiler.cmake b/Modules/CMakeDetermineCUDACompiler.cmake index 6bdd06b..e60a973 100644 --- a/Modules/CMakeDetermineCUDACompiler.cmake +++ b/Modules/CMakeDetermineCUDACompiler.cmake @@ -300,7 +300,7 @@ elseif(CMAKE_CUDA_COMPILER_ID STREQUAL "Clang") endforeach() endif() - # Find target directory.
