./configure for emacs not finding programs on MSYS2

I am trying to build emacs with native compilation from source in MYSY2 on Windows 11, on my first try I got some warnings when running ./configure, nevertheless I tried to continue, then invoking make and make install, as far as I could see I got no errors, but the process did not generate any executable anywhere.

Then I tried again after cleaning the previous attempt with make distclean, but now it seems like the necessary programs are not cited in $PATH anymore, as trying to run ./configure now gives me an error of not finding any compiler. To try to solve this I simply typed packman -S gcc and after that the ./configure found gcc, but then it gave an error about not finding a library of imagemagick ( I was building with --with-imagemagick) but running pacman -S mingw-w64-x86_64-imagemagick I got that I already had imagemagick installed, pacman reinstalled imagemagick but the same error persisted, then I decided to remove --with-imagemagick.

Now it gives a error saying that to build with native compilation I need zlib, but by checking with pacman -S mingw-w64-x86_64-zlib it also said that I already had zlib, it kept giving the error, then I decided to run packman -S zlib which worked in installing or re-installing the package (I am not sure), but I keep getting the error about missing the zlib library.

Hence it seems that the installed libraries and programs appear to have been taken out of $PATH. Actually, looking again at the results I got, it seems that I should be using the mingw-w64-x86_64-gcc package instead of simply gcc I have mingw-w64-x86_64-gcc installed since before using ./configure the first time, when I was setting up the necessary tools to build emacs (as I did mingw-w64-x86_64-zlib and mingw-w64-x86_64-imagemagick). And, in fact when running ./configure it checks for mingw-w64-x86_64-gcc but doesn't find, finding only the gcc that I installed after running make distclean.

How can I make ./configure find the programs and libraries that it needs to make the MAKEFILEs?

For some reason MSYS2 doesn't try to add the folder in which the Linux adapted programs end up in PATH.

So doing a simple export PATH=/mingw64/bin:$PATH solved my problem. Also I uninstalled the non-mingw gcc. Not sure if the mingw gcc and the program that installs as gcc are different, they probably are, but what sense does it make to make available a incompatible version of gcc?
