Subject: [PATCH] ENH: Auto-dependency generation support for CUDA files. Only
performed if nvcc is present. CUDA outputs can be directed into a separate
directory, which can be specified via CUDABUILDDIR

+#
+# It is assumed that this script is executed from a
+# project directory (i.e. the project directory is the cwd).
+#
+# Automatically generate Make rules and dependencies for
+# all source files in the project. This creates a file
+# called depend.mk which contains a rule for every object
+# file to be compiled, which has all header files
+# that the source file includes as dependencies. If
+# object files are to be saved into a separate build
+# directory, the project Makefile should set the BUILDDIR
+# variable.
+#
+# If the NVCC environment variable is set to a nvcc compiler,
+# rules are generated for CUDA .cu files. If CUDA object files
+# are to be saved into a separate build directory, the project
+# Makefile should set the CUDABUILDDIR variable.
