It works perfectly - thanks!

Re: [CMake] how do you allow CMAKE_CUDA_COMPILER to be optional via project LANGUAGE?
The way Eric suggest with check_language is what I use when I want to conditionally support CUDA.

[CMake] how do you allow CMAKE_CUDA_COMPILER to be optional via project LANGUAGE?
Hi all, So this question is again about project(foo LANGUAGES CXX CUDA). Is it possible to switch off CUDA if Cmake couldn't find CUDA compiler? I.e. something along the line: if (CUDA_FOUND) set_language_to_CUDA_and_CXX else(CUDA_FOUND) set_language_to_CXX_only endif(CUDA_FOUND) The main reason is I don't want CMake to fail when CUDA compiler isn't available. Rather, it should continue to compile the source files using CPP compilers instead.
