[pgrouting-dev] Patch for CMakeLists.txt to support more Postgres variants

[Sandeep Thakkar]

Hi,

I was trying to compile pgRouting-3.3.1 against EnterpriseDB Postgres
(EPAS) on Rocky Linux 8 instance and the build failed with the following
error:

CMake Error at CMakeLists.txt:183 (message):
>    PostgreSQL 9.2.0 or greater is required.


Attached is the patch for CMakeLists.txt to support additional Postgres
variants along with community PostgreSQL. If there is a better way to
submit the patch (https://docs.pgrouting.org/doxygen/ ?) then do let me
know and I'll be happy to do that.

    So instead of string substring, use string regex match to get the

    Tested on Linux
