How to put several paths in CMAKE_PREFIX_PATH? [duplicate]

Question

How can I have several paths for cmake to look for needed libraries. I installed zlib and libpng under /usr/local/zlib and /usr/local/libpng however, what I'm currently doing is first cmake -DCMAKE_PREFIX_PATH=/usr/local/zlib, then issuing a second command `cmake -DCMAKE_PREFIX_PATH=/usr/local/libpng" in order for cmake to recognize both. Is there a way to have both paths in the same variable?

I tried -DCMAKE_PREFIX_PATH=/usr/local/zlib:/usr/local/libpng but it didn't work.

You need to use ; character instead of : to define lists.
