Due to raising the minimum CMake version to 3.14, we can now run the CMake build verification (ci_verify_cmake.sh) from the libpng source dir, just as in the other scripts (ci_verify_*.sh). This is possible thanks to the modern CMake command options `cmake -B` and `cmake -S`. We can finally simplify the implementation of ci_verify_cmake.sh by removing a code complication that was annoying, and yet, necessary in peculiar Bash-on-Windows setups. Fun fact: CMake version 3.14 was released on 2019-03-14. Reportedly, on purpose! This is a cherry-pick of commit 558dfbb7570cb74205f978f11504b217a2c03c2c from branch 'libpng18'.
