Has anyone encountered the same problem as me？

I just changed lines 21-28 in CMakeLists to:

if (CMAKE_COMPILER_IS_GNUCC)
execute_process(COMMAND ${CMAKE_C_COMPILER} -dumpversion
OUTPUT_VARIABLE GCC_VERSION)
string(REGEX MATCHALL "[0-9]+" GCC_VERSION_COMPONENTS ${GCC_VERSION})
list(GET GCC_VERSION_COMPONENTS 0 GCC_MAJOR)
list(GET GCC_VERSION_COMPONENTS 0 GCC_MINOR)

message(STATUS "GCC Major Version is " ${GCC_MAJOR})
message(STATUS "GCC Major Version is " ${GCC_MINOR})

endif()
