Save the CMake executable in our MM config file.

• This allows us to provide a non-default CMake executable to our autoconf config or CMake config. OpenModelica now remembers this selection and uses that exact CMake executable for all its internal uses as well.

• Improves external library not included in FMU generation #9509.

How does this work? What do I need to do if I want to use CMake from C:/Program Files/CMake/bin/cmake.exe on a Windows system?

[mahge]

You just configure OpenModelica with that CMake

"C:/Program Files/CMake/bin/cmake.exe" -G "MSYS Makefiles" ....

and compile as usual. OpenModelica saves that CMake exe path and will use it instead of just issuing "cmake" and relying on CMake being on PATH.

Basically, all the commands that were using "cmake ...." are now changed to the form Autconf.cmake + "..." instead. Autconf.cmake is initialized from the CMake exe you used to configure OpenModelica with.

LGTM

I don't understand where I can change this configuration. Is it command line? what does means the "...." ?
Is it to compile a new complete openmodelica? Or only the model?

This PR makes it possible to self-build OpenModelica with some CMake executable on Windows and after that this CMake executable will be used for FMU compilation as well.

So it is a first step, but unless you are self-building OpenModelica from source it isn't useful for the end user.
