I was planning on fixing a bug related to flags and separable compilation
for FindCUDA when I discovered something peculiar. I'm asking here in case
I missed something with how source files are processed.
I branched off of origin/master this morning.
I have a macro that generates some custom commands for building object
files for cuda (found in FindCUDA.cmake).
CUDA_COMPILE(CUDA_FILES test_bin.cu)
message("CUDA_FILES = ${CUDA_FILES}")
ADD_EXECUTABLE(cuda_compile_example
${CUDA_FILES}
${source_files}
main.cc
external_dependency.h
)
When print out CUDA_FILES I get a full path:
CUDA_FILES =
/Users/jbigler/code/FindCUDA/build-cmake-git/src/CMakeFiles/cuda_compile.dir//./cuda_compile_generated_test_bin.cu.o
Great!
When I try to compile cuda_compile_example I get this, though:
make[2]: *** No rule to make target
`src/CMakeFiles/cuda_compile.dir/cuda_compile_generated_test_bin.cu.o',
needed by `src/cuda_compile_example'. Stop.
What I don't see in my makefiles is the build rule for the object file.
I can provide a reproducer, but it would require having CUDA installed.
This is for OSX 10.8 with Xcode 5.1 (command line utils, so Makefile).
