tweak to CMakeLists.txt for Fedora 27

[bengland2]

This is what I did to get this repo to build on Fedora 27:

$ git diff
diff --git a/CMakeLists.txt b/CMakeLists.txt
index 580758a..2b8d9d0 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

 else()

 endif()

am running with glfw-3.2.1-6.fc27.x86_64 RPM. Is this supported? I am seeing some segfaults in some of the example programs. Thx again for the book.

There's a slightly better & more portable fix for this, in Pull Request #13.

I recommend cloning the repo and merging in Pull Request's #5 and #7, as well.

If anyone were actively merging in PRs, I'd do some cleanup and submit them. My goal was basically to make CMake behave in a more typical fashion and exclude the bundled version of glfw. On that point, note that I initially fixed glfw the same way as you did.

I had to do this exact same thing for CentOS7, see issue #37.
