issue with building on macOS

[Agrrox]

Hello I get the following error when I try to build the program.

mac:build macpro$ make -j

Hello what is your compiler version ? It might be outdated ! I also know some people have issues with the PNG library on macOS so let me know if you see any of those and I'll do my best to help you with that too.

macOS: 10.13.6 High Sierra CMake 3.23.0 libpng 1.6.37

None of those are compilers. Please include the output of:

cd <mcmap repo>
cmake -S . -B newbuild

On my machine:

mcmap> cmake -S . -B newbuild

  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has

  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" with any of

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.

Hey so as you can see the compiler (AppleClang) version is 9.x, so it is not compatible to compile mcmap with :/ Please upgrade it using Xcode or install another compiler using brew. All of that is detailed in the README.
