CMAKE_CUDA_HOST_COMPILERΒΆ
New in version 3.10.
When CMAKE_CUDA_COMPILER_ID
is
NVIDIA
, CMAKE_CUDA_HOST_COMPILER
selects the compiler executable to use
when compiling host code for CUDA
language files.
This maps to the nvcc -ccbin
option.
The CMAKE_CUDA_HOST_COMPILER
variable may be set explicitly before CUDA is
first enabled by a project()
or enable_language()
command.
This can be done via -DCMAKE_CUDA_HOST_COMPILER=...
on the command line
or in a toolchain file. Or, one may set
the CUDAHOSTCXX
environment variable to provide a default value.
Once the CUDA language is enabled, the CMAKE_CUDA_HOST_COMPILER
variable
is read-only and changes to it are undefined behavior.
Note
Since CMAKE_CUDA_HOST_COMPILER
is meaningful only when the
CMAKE_CUDA_COMPILER_ID
is NVIDIA
,
it does not make sense to set CMAKE_CUDA_HOST_COMPILER
without also
setting CMAKE_CUDA_COMPILER
to NVCC.
Note
Ignored when using Visual Studio Generators.
