Summary0014078: FindCUDA "-D${cuda_target}_EXPORTS" generates invalid identifier
DescriptionI use CMake as out-of-source-build way, and that's why my cuda_add_library call looks like this:

cuda_add_library(../models/program_gpu ../models/program_gpu.cu MODULE)

Because it's built as a MODULE, the following line applies in FindCUDA.cmake:
if(_cuda_build_shared_libs)
  list(APPEND nvcc_flags "-D${cuda_target}_EXPORTS")
endif()

It generates the following:
/usr/local/cuda-5.0/bin/nvcc [...] -D../models/program_gpu_EXPORTS [...]

Apart from that fact it's not useful, the C standard says it's not valid also. So I got the following error message from nvcc:
<command-line>:0:1: error: macro names must be identifiers

I've just realized that the first parameter is just a name and can be anything. It's my fault, it's not really a bug.

I can't close this report myself, but I'm sorry for the unnecessary noise.
