CMake policy CMP0074

[kostya416]

I am using set (PostgreSQL_ROOT "xxxxx") in my CMake file and getting following warning / error from CMake:

CMake Warning (dev) at 3rd-party/taopq/CMakeLists.txt:12 (find_package):
Policy CMP0074 is not set: find_package uses _ROOT variables.

it can be fixed by adding following lines to CMakeLists.txt for taopq before find_package call:

if (POLICY CMP0074)
cmake_policy(SET CMP0074 NEW)
endif()

@kostya416 Thank you for reporting your case, but I would prefer not customizing CMP0074 only due PostgreSQL_ROOT.

What could be done is moving taopq to use CMake targets instead, following the official CMake modules: https://cmake.org/cmake/help/latest/module/FindPostgreSQL.html#imported-targets
