[cmake-developers] Compiling static/stand-alone CMake.exe

[Kyle Edwards]

Venedict,
To relocate cmake.exe, it's not sufficient to just copy the executable
- you have to install all of the modules along with it. You do this by
running the "install" target.
Given a path to where you want to put CMake, you would build it like
this:
cmake C:/Path/To/CMake/Source
-DCMAKE_INSTALL_PREFIX=C:/Path/To/Where/I/Want/To/Install
cmake --build .
cmake --build . --target install
This will install cmake.exe along with all of its dependencies.
