    Using MinGW containing the GCC GNU Compiler Collection and CMake to build OpenGL game projects using GLFW. GLM, Boost, LibPNG and ZLib.
ZLib

Get zlib sources and use the certutil executable to verify the SHA256 signature:
certutil -hashfile zlibx.zip SHA256
Run CMake:
mkdir build
cd build 
cmake ..
Seems to be a problem with windres.exe path, had to manually shorten the path for this otherwise was getting error during build:
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\windres.exe: preprocessing failed.
mingw32-make.exe[2]: *** [CMakeFiles\zlib.dir\build.make:61: zlib1rc.obj] Error 1
mingw32-make.exe[1]: *** [CMakeFiles\Makefile2:108: CMakeFiles/zlib.dir/all] Error 2
mingw32-make.exe[1]: *** Waiting for unfinished jobs...

Updated build.make manually.
Run CMake install.
LibPNG, GLFW and GLM

Get libpng, glfw, glm sources.
Use certutil as per.
CMake build install each.
Boost

Boost is a chunky one, again get the sources and certutil.
Get the zip or (or recommended 7z) for the Boost sources and extract them to C:\Program Files\Boost\boost_x_x_x\ where the x_x_x corresponds to the Boost version you have downloaded.
Change directory to the boost directory and run bootstrap in that directory. First, check that g++ is on your PATH. Update environment variables as necessary. Then run the command:
b2 address-model=64 architecture=x86 toolset=gcc variant=debug link=shared runtime-link=shared --build-type=complete install
Using in a CMake project
