Description Mark 2020-12-15 12:20:23 UTC 
SUMMARY
Trying to "make install" on windows with MinGW results in:
> Microsoft Windows [Version 10.0.18363.1256]
> (c) 2019 Microsoft Corporation. All rights reserved.

Aka, it does nothing.

Make install executes:
> install: preinstall
> 	@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --cyan "Install > the project..."
> 	"C:\Program Files\CMake\bin\cmake.exe" -P cmake_install.cmake
> .PHONY : install

The preinstall executes:
> preinstall: all
>	$(MAKE) $(MAKESILENT) -f CMakeFiles\Makefile2 preinstall
> .PHONY : preinstall

For whatever reason, that preinstall isn't working.
If i directly execute:
> "C:\Program Files\CMake\bin\cmake.exe" -P cmake_install.cmake

And thus manually do what make install should do then it works as expected.


STEPS TO REPRODUCE
1. Have a Windows 10 x64 with mingw installed (i had the one that came with Qt: mingw81_64)
2. Make sure that your environment variables are set correctly (make --version should show something)
3. Create a "c:\kderoot" folder. Or adjust below accordingly.
4. open a cmd window
5. git clone https://invent.kde.org/frameworks/extra-cmake-modules.git (somewhere)
6. In your extra-cmake-modules git clone dir type: mkdir build && cd build && cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:\kderoot;
6. make install

OBSERVED RESULT
> Microsoft Windows [Version 10.0.18363.1256]
> (c) 2019 Microsoft Corporation. All rights reserved.

EXPECTED RESULT
List of files that are installed to the set CMAKE_INSTALL_PREFIX.

SOFTWARE/OS VERSIONS
Windows: 10 x64
Qt Version: 5.15.1 (for mingw)

ADDITIONAL INFORMATION
It would be super helpful if https://api.kde.org/ecm/manual/ecm.7.html would include installation instructions for windows. On linux this is easy, just install it using your package manager and you're done. Windows is.... much more primitive. Which is ironic :)

Comment 2 Mark 2020-12-15 15:18:34 UTC 
While you have it working (that's awesome!) you're not using my steps to reproduce at all!

You use ninja (i don't have ninja).
You add a bunch of defines, i didn't.

Now that might be fine! I just don't know.
Would you care explaining how it's "supposed" to work under mingw with windows?

Sadly the instructions don't exist for it (see https://api.kde.org/ecm/manual/ecm.7.html or the lack thereof)
Comment 3 Hannah von Reth 2020-12-15 15:52:44 UTC 
In that case please provide you complete log, including your cmake call.
