CUDA 3.2 on Windows systems changed the layout of the library paths. This adds the extra
directories needed to locate the new files.
I also explicitly disable emulation mode for CUDA 3.1+. This feature was deprecated in
3.0 and ultimately removed in 3.1. The script errors out if CUDA_BUILD_EMULATION is
turned on. I didn't want to ignore emulation mode (even with a warning - which most
people may not even see) and have users confused as to why it wasn't working.
In version 3.0 of the CUDA toolkit when building code for emulation, you need to link
against a new version of the cuda run time library called cudartemu. This CL adds a check
for the new library and uses it when present and in emulation mode. Note that this
library is not present in previous or subsequent versions of the CUDA toolkit.
CUDA_VERSION_MAJOR and CUDA_VERSION_MINOR were only computed when CUDA_VERSION was first
computed. Subsequent runs of FindCUDA would not have CUDA_VERSION_MAJOR/MINOR set. We
now extract the major and minor versions from the CUDA_VERSION cache variable every run.
BUILD_SHARED_LIBS is now only recognized when calling CUDA_ADD_LIBRARY. If you want the CMAKE_SHARED_LIBRARY_C/CXX_FLAGS to be used, pass SHARED as an argument. This prevents -fPIC from being used on objects destined for executables by default.
Cutil was never intented to be used outside of the SDK. The removal of this
code is in support of this. The CUDA_SDK_ROOT_DIR will continue to be
supported, in case users wish to use this to find files in the SDK. There are
also two examples of how to use CUDA_SDK_ROOT_DIR to find header files and
libraries if users so wish.
The CUDA_PROPAGATE_HOST_FLAGS was incorrect in that it prevented the CUDA_NVCC_FLAGS_CONFIG variable from getting filled.
Also, added a search path for the CUDA SDK install on Macs.
- Finished updating and formatting documentation.
- Added CUDA_PROPAGATE_HOST_FLAGS (Default ON) that can disable the C flag
propagation to the host compiler.
_ Changed the output directory for support files from
${CMAKE_CURRENT_BINARY_DIR} to ${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles. This
will hopefully reduce the clutter in the binary directory.
