Bug ID: 44971
Summary: Not able to disable CUDA offloading
Product: Build scripts
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: cmake
Assignee: unassignedb...@nondot.org
Reporter: alexander.gr...@tu-dresden.de
CC: llvm-bugs@lists.llvm.org
The CMake build system only allows to enable or disable the OpenMP target
offloading completely via OPENMP_ENABLE_LIBOMPTARGET. But it is not possible to
disable a specific backend, e.g. CUDA. If CMake finds CUDA it will be enabled
even if the CUDA found is not what is wanted. This may lead to e.g.

--> There should be an option to disable specific backends, at least once that
require some external dependency (e.g CUDA)
