Optikos covered where to get msys2 (it is the preferred now adays due to it 
being 64bit).  What I generally do is:

1.  Install the necessary tools:
pacman -Sy make
pacman -Sy mingw-w64-x86_64-toolchain

That should get everything.  If it doesn't get GNAT for some reason, then
search pacman for gcc-ada and install that package.

2.  Install GNAT community 2018 or newer.  There is no gprbuild in msys2
and sometimes it is hard to build.  By installing GNAT community, you 
can get gprbuild.  I accomplish this by adding the bin directory for 
GNAT Community to the *end* of the path.  This ensures using GCC uses
the msys version but gprbuild can still be used.

I was recently able to successfully build gprbuild for msys2, but I 
would not recommend it to start out until you are comfortable with
the environment.
