+# Synopsis:
+# CUDA_SELECT_NVCC_ARCH_FLAGS(out_variable [target_CUDA_architectures])
+# -- Selects GPU arch flags for nvcc based on target_CUDA_architectures
+# target_CUDA_architectures : Auto | Common | All | LIST(ARCH_AND_PTX ...)
+# - "Auto" detects local machine GPU compute arch at runtime.
+# - "Common" and "All" cover common and entire subsets of architectures
+# ARCH_AND_PTX : NAME | NUM.NUM | NUM.NUM(NUM.NUM) | NUM.NUM+PTX
+# NAME: Fermi Kepler Maxwell Kepler+Tegra Kepler+Tesla Maxwell+Tegra Pascal
+# NUM: Any number. Only those pairs are currently accepted by NVCC though:
+# 2.0 2.1 3.0 3.2 3.5 3.7 5.0 5.2 5.3 6.0 6.2
+# Returns LIST of flags to be added to CUDA_NVCC_FLAGS in ${out_variable}
+# Additionally, sets ${out_variable}_readable to the resulting numeric list
+# Example:
+# CUDA_SELECT_NVCC_ARCH_FLAGS(ARCH_FLAGS 3.0 3.5+PTX 5.2(5.0) Maxwell)
+# LIST(APPEND CUDA_NVCC_FLAGS ${ARCH_FLAGS})
+#
