Mani,

Sorry, the CMakeLists.txt files built for pgrouting 2.x were not 
designed for support multiple versions installed on the same system. 
This is a problem for me because I have 9.2, 9.3, and 9.4 installed and 
I can only build and install on 9.4.

The solution id to update the CMakeLists.txt and specifically 
cmake/FindPostgreSQL.cmake which so you can do something like

cd build
cmake -DUSE_PG=9.x ..

I took a quick look at doing this a while back but 
cmake/FindPostgreSQL.cmake needs to be replaced and other changes are 
needed and I didn't have time to make the changes and get it working.

tools/test-runner.pl already support options for pg versions and ports 
so only the build system is broken in this regard.

If you want to read up on CMake and get this working a pull request 
would be great!
