Be aware that MSYS2 environment is a "dual" environment: * Unix like environment. Executables are in <MSYS2_ROOT>/usr/bin * Windows like (i.e. understand windows paths but with slashes rather than back-slashes). Executables are in <MSYS2_ROOT>/ mingw(64|32)/bin.
So, if you want a pure unix like usage, you have to install package 'msys/cmake'. If you use tool in mingw(32|64)/bin (package 'mingw32/mingw-w64-i686-cmake' or ' mingw64/mingw-w64-x86_64-cmake'), use windows paths (ex: C:/DESTDIR/lib/cmake).

I am pretty Hmm, I don't think I have a native Windows cmake installed. I installed mingw-w64-*-cmake from pacman, and I do not find any other cmake.exe in PATH or on the hard disk. At least when I do: #> find /c/ /d/ -name cmake.exe 2>/dev/zero /d/msys2/bda/mingw32/bin/cmake.exe /d/msys2/bda/mingw64/bin/cmake.exe I find only the native MSYS2 mingw-w64-x86_64-cmake / mingw-w64-xi686-cmake.
