Summary:                    pkg_check_modules should document how to handle
spaces in framework names
Description: 
pc files don't often have spaces in values, but it does happen (especially on
the Mac), and a little guidance would be helpful. 

http://kegel.com/cmake/spaces-in-framework-names/ is a worked example
of how to cope with framework names that contain spaces.  The idea is:
- the .pc file should use a backslash in front of each space in the name
(quotes don't seem to work)
- the CMakeLists.txt should use string(REPLACE...) to replace semicolons
with spaces and/or single quote marks, as appropriate

For instance:

string(REPLACE "-framework;foo;bar" "-framework 'foo bar'" foo_LDFLAGS
"${foo_LDFLAGS}")

Steps to Reproduce: 
On a mac:
$ tar -xzvf spaces-in-framework-names.tgz
$ cd spaces-in-framework-names
# comment out the string(REPLACE...) in CMakeLists.txt to demonstrate problem
$ sh demo.sh
