This variable affects how
find_* commands choose between
OS X Frameworks and unix-style package components.
On Darwin or systems supporting OS X Frameworks, the
CMAKE_FIND_FRAMEWORK variable can be set to empty or
one of the following:
- Try to find frameworks before standard libraries or headers. This is the default on Darwin.
- Try to find frameworks after standard libraries or headers.
- Only try to find frameworks.
- Never try to find frameworks.
