I am triing to build Assimp with CodeBlocks and MINGW as static lib. Have downloaded the latest avaible version (5.0.1) and created a makefile for CodeBlocks using cmake-gui. I am able to open that file with CodeBlocks, but when I am triing to build iit fails. Here the complete log:

I am not really familiar with al that build stuf, but looks like there is some problem with zlib. How can I fix that problem and build the lib with the compiler I have? Don´t want to switch to msys2 or any other compiler. However if there is no way to compile it with MINGW, I am ready to switch to some other C++ API with the same features.

There is 1 line in that log which is alway in the language of the OS:

Der Befehl "C:\Program" ist entweder falsch geschrieben oder konnte nicht gefunden werden.

The translation is:

The command "C: \ Program" is either misspelled or could not be found
