But the version is opencv 2.3.

You cannot install 2 versions and run both, you can swap between them, but no running both the same time.

if you can live with static linking (cmake -DBUILD_SHARED_LIBS=OFF) and choose a custom install dir (like cmake -DCMAKE_INSTALL_PREFIX=/home/me/opencv23) when building opencv23 (or any other version) it should be a breeze.

later just use cmake to generate projects, and export OpenCV_DIR=/home/me/opencv23 before running cmake.

I find this
cmake -DBUILD_SHARED_LIBS=OFF, is necessary？

i might be wrong, but i think, it is nessecary, else you will have to tell your program at runtime, where to look for the so's.
