The easiest way is to install the Git bridge, while maintaining the Git installation in a custom directory, which you can easily do using the Portable app for official Git for Windows (that is, you can simply unzip it anywhere).
From there, using your Git installation, you will mainly find global configuration settings that are located in %HOME%/.gitconfig . So make sure you have HOME , and bot Git (yours and the one installed by the bridge) will use them.
Now, if you do not need a portable installation (or a complete recompilation, for example, edwinf , suggest in his answer ), then ferventcoder (a member of the chocolate organization ) offers to look / comment on issue 131 in a comment:
Add a switch to ignore dependencies during installation (something like -ignoredependencies )
