Add msvc default build rule #17
Description
It is time to start building other projekts on windows.
Considerations
When compiling with msvc, it differs from compiling with gcc or clang. More specificaly, when compiling with gcc or clang generating the .o-file and the .pcm-file is two separate steps, but building with msvc this is done with a single step.
Compiling with msvc is something similar to this
cl /c /EHsc /RTC1 /MDd /std:c++latest /ifcOutput "test2.cppm.ifc" /Fo"test.obj" /Fd"vc142.pdb" /Gd /interface /analyze- /FC /TP "test2.cppm"
Note there that the precompiled file is called ifc here.. It is possible to rename it to pcm, but i do not know if it is possible to use it then. Note also that if there is no export module ...;-statement in a file, no ifc is generated.
