I did some additional test to see if in any of them I could see the progress capture to try to see if I can see what gmake uses. From several attemps I was able to do it:

1) In a CMD window enter into the niosv shell: C:\intelFPGA_pro\23.4\niosv\bin\niosv-shell.exe

2) In this CMD window, run the cmake command: cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -B soft2/app/debug -S soft2/app

3) Open RiscFree by double-clicking on the .exe file (not under the niosV shell) and create the C/C++ Cmake project as indicated in the Macnica application note.

4) In Riscfree, build the project. In this case, I see that this fails with the error seen in Test1 above. Close RiscFree.

5) In this CMD window in which the niosv shell is running, open RiscFree using the same workspace used when the project was created.

6) Build this project again. This time the build succeds and now it shows the progress capture as shown next:

Here I can see that it uses the make.exe that is included as part of the RiscFree installation at C:\intelFPGA_pro\23.4\riscfree\build_tools\\bin\\make.exe

Repeating this in Linux, I see that it uses /usr/bin/gmake. I am guessing that perhaps it tries to find gmake and in case it doesn't exist it goes to find make. In Windows I don't have gmake so, perhaps it uses the make included in Riscfree.

I think that you can try to remove the Matlab path from the Windows corresponding $PATH environment and see if this time it uses the make from the RiscFree installation.
