Consider copying make.exe to mingw32-make.exe

[StephanTLavavej]

CMake is reportedly unhappy without this.

I always do this manually with a symlink every time I install this distro, +1

@LB-- , if you could provide a CMake file and command line for a Hello World C++ file, that would help me validate this. I know how to obtain CMake binaries (which I used to have to do while building the distro), but I know nothing about writing stuff for CMake, and I want to read as little of its documentation as possible (just figuring out how to pass compiler options through it for libjpeg-turbo was excruciating).

Create this CMakeLists.txt in a directory with a file named hello.cpp:

cmake_minimum_required(VERSION 3.1)

project(nuwen-hello)

add_executable(hello hello.cpp)
set_property(TARGET hello PROPERTY CXX_STANDARD 14)

After a clean install of the distro:

>cmake -G "MinGW Makefiles" .
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

Delete any files that got created. After symlinking or copying make.exe to mingw32-make.exe:

>cmake -G "MinGW Makefiles" .

After that you may run cmake --build . to build the program.

Thank you, @LB-- , that was extremely helpful.
