Re: [CMake] CMAKE doesn't pass NVCC flags?
I see - thanks! This is working now for 3.11 with CMAKE_CUDA_FLAGS.

Re: [CMake] CMAKE doesn't pass NVCC flags?
I think you are mixing old and new approaches. Since you have enabled the
CUDA language (via your project(...) call), you should be using either
CUDAFLAGS or CMAKE_CUDA_FLAGS.
I think CUDA_NVCC_FLAGS is only used for the old cuda_add_library or
executable functions.
Note that finding the cuda package should no longer be necessary. If you
support non-CUDA builds you should use CheckLanguage and
enable_language(CUDA), and remove CUDA from the project(...) call.
Currently if nvcc is not found, configuration will fail because you have
CUDA in the project command which makes it required.
Hope that helps!

[CMake] CMAKE doesn't pass NVCC flags?
So, it doesn't seem that my setting in NVCC flags is being used:
In CMakeLists.txt:
project(tangram LANGUAGES CXX CUDA)
[...]
FIND_PACKAGE(CUDA REQUIRED)
if(CUDA_FOUND)
add_definitions(-DCUDA_CALLABLE="__host__ __device__")
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-Xcompiler="-fopenmp -fPIC")
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};--std=c++11
--expt-relaxed-constexpr)
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode
arch=compute_70,code=sm_70)
set(CUDA_PROPAGATE_HOST_FLAGS ON)
set(CUDA_SEPARABLE_COMPILATION OFF)
message(STATUS "CUDA include directories ${CUDA_INCLUDE_DIRS}")
message(STATUS "Overwriting THRUST_DIR to point to
${CUDA_INCLUDE_DIRS}/thrust")
set(THRUST_DIR "${CUDA_INCLUDE_DIRS}")
set(EXTRA_LIBS ${CUDA_LIBRARIES})
message("CUDA flags" ${CUDA_NVCC_FLAGS})
else(CUDA_FOUND)
message(FATAL "CUDA not found")
endif(CUDA_FOUND)
[...]
Then, at cmake stage:
[...]
-- Overwriting THRUST_DIR to point to
/projects/opt/centos7/cuda/9.0/include/thrust
CUDA flags-Xcompiler="-fopenmp
-fPIC"--std=c++11--expt-relaxed-constexpr-gencodearch=compute_70,code=sm_70
-- Adding application directory app
[...]
But then, build fail, and when I do make VERBOSE=1:
[...]

app/simple-vfgen-cuda/CMakeFiles/simple-vfgen-cuda.dir/simple-vfgen-cuda.cu.o

-o CMakeFiles/simple-vfgen-cuda.dir/simple-vfgen-cuda.cu.o
[...]
None of the flags was passed into nvcc. This is with cmake/3.11.1. Does
upgrading to 3.12 recommended to solve the issue?
Thanks,
