Hi, guys,
I am a learner of CMake, and I find that CMake would only compile .cu files with nvcc, except any files with the other extensions.
Is this rule exlicitly described in the CMake documentation?
Currently, I have not been able to find relevant content.

Your answer and sharing will be appreciated!

.cu files by default are mapped to the CUDA language. CMake supports compiling CUDA sources with either nvcc and clang which is documented at: https://cmake.org/cmake/help/latest/manual/cmake-compile-features.7.html

If you want to compile a .cu file as a C++ source you would set the LANGUAGE source file property to CXX.
