BUG #16343: Build problem: Install.pm "Could not find debug or release binaries"

The following bug has been logged on the website:

Bug reference:      16343
Logged by:          Arnold Müller
Email address:      noeld.mueller@googlemail.com
PostgreSQL version: 12.0
Operating system:   Windows 10 Home
Description:

During a build with vcpkg I got above error message during the install phase
after a successfull build phase.
(I tried to install
 ulibpq:x64-windows                                  12.0-1
)

It turned out that I got another, completely unrelated configure-file 7
folders up the hierarchy.
Inserting an elsif fixed it.

So, please consider merging this one into the Install.pm. It worked for me
on Windows 10 Home with vcpkg/MSVC, haven't tried it on other platforms,
though.

Thanks,
Arnold
