Question

Zlib is supposed to be installed on all mac’s by default I’m pretty sure.. But when I run cmake for SFML I get the following errors:

The C compiler identification is Clang 4.1.0
The CXX compiler identification is Clang 4.1.0

Help CMake to locate it by setting ZLIB_INCLUDE_DIR variable. Either run this:

cmake -D ZLIB_INCLUDE_DIR=/path/to/zlib/include .

in your build directory, or set it via GUI.
