what is the correct way to use cmake

Question

I was following instructions for compiling a software in windows as described here: https://github.com/solvespace/solvespace . But when i launch the first cmake command it points out the following:

$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw64.cmake -DCMAKE_BUILD_TYPE=Release
CMake Error at CMakeLists.txt:42 (project):
  Running

   'nmake' '-?'

  failed with:

   Impossibile trovare il file specificato


-- Configuring incomplete, errors occurred!
See also "C:/Users/user/Documents/experiments/SolveSpaceFolder/solvespace/build/CMakeFiles/CMakeOutput.log".

i've alredy installed mingw64 and added to PATH, in fact it work alone. Moreover I can see that there is nmake implied. I just can't figure out what's the problem.

Answer 1

Remove CMakeCache.txt and try to set the generator

cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw64.cmake -DCMAKE_BUILD_TYPE=Release -G "MinGW Makefiles"
