I also have a small experience of using the MSYS2 project.
I will try to share my experience.

Which generator did you use?

Try to use the "MSYS Makefiles":

cmake -G"MSYS Makefiles" ...

Many examples of different projects you can find here:

I have the assumption that CMake is not correctly determined by the generator by default
for this environment. But I'm no expert and this question still needs further study.

For publicity will say that I have a project osgQtQuick:

https://github.com/podsvirov/osgqtquick

This project is now included in MSYS2. Here is a script build the package:
