Or any include directory/library.
I use cmake gui tool so I run it and usually the gui will highlight the include or library it can't find and let you open a open dialog to set the path however it doesn't do that for this cmake cofig it tell you in red text in the output in the gui tool, so,
CMake Error at C:/Program Files/CMake/share/cmake-3.0/Modules/FindPackageHandleStandardArgs.cmake:136 (message):
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.0/Modules/FindPackageHandleStandardArgs.cmake:343 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.0/Modules/FindZLIB.cmake:101 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
src/CMakeLists.txt:7 (find_package)
So still using the gui how do I point cmake to the zlib include dir?
Quick solution: apt-get install zlib1g-dev
