Ensure source/build paths appear first in CUDA compilation
Reported by @jlima: If a VecGeom install is present in a path that's added to include_directories, this will appear first in the set of -I
paths passed to nvcc
. These will be found/used in place of the project local ones, causing compile errors.
Triaged to FindCUDA
not respecting the CMake variable CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE
when creating the overall include paths.
Call cuda_include_directories
with project source and binary directories before cuda_add_library
to ensure these are at the front on the include search path for nvcc
. Minor hack as cuda_include_directories
is usually intended for .cu/.cuh
files. Temporary until migration to CMake native CUDA support.
Should not cause issues in testing, but @jlima should confirm this fixes his issue before merging!
