 * If the environment variable is already set, then it left as is to respect
 * the wishes of the user.
 *
 * The path is determined by attempting to find the path modules/packages3d
 * files in kicad tree.
 * This may or may not be the best path but it provides the best solution for
 * backwards compatibility with the previous 3D shapes search path implementation.

 * Otherwise, the kicad path is not known (Windows specific)

 * @param aKiSys3Dmod = the value of environment variable, typically "KISYS3DMOD"
 * @param aProcess = the current process
 * @return false if the aKiSys3Dmod path is not valid.
