CMake installation issues with soci as a dependency

[jonasbhjulstad]

I get the following error when trying to install my library (SBM_Database)

CMake Error at _deps/soci-build/src/backends/empty/cmake_install.cmake:61 (file):
  file INSTALL cannot find
  "/home/man/Documents/SBM_Database/build/lib/libsoci_empty.so.4.1.0": No
  such file or directory.
Call Stack (most recent call first):
  _deps/soci-build/src/backends/cmake_install.cmake:47 (include)
  _deps/soci-build/src/cmake_install.cmake:52 (include)
  _deps/soci-build/cmake_install.cmake:51 (include)
  cmake_install.cmake:52 (include)

Soci was fetched using the following:

CPMFindPackage(
    NAME Soci
    GITHUB_REPOSITORY SOCI/soci
    GIT_TAG master
    OPTIONS
    "WITH_POSTGRESQL ON"
)

That same issue needs to be circumventend in the package for Arch Linux. Take a look at it.

Sorry, no idea what's going on here and no time to debug it right now but if anybody has a fix, it would be welcome, of course.

SOCI's install routines are completely rewritten in #1118 - I'm assuming that the present issue is fixed with my PR until proven otherwise, i.e. please try it out and report back
