Using the latest Android NDK (r14) w/ clang 3.8.275480, oglplu2 doesn't build.

[mattgruenke]

Using the latest git version of oglplu2 (revision 4068d65b534dbdc0108c6b0f50b9a9e8d4d06eb3) fails on:

CMake Error at config/StdFixes.cmake:194 (message):
  Failed to fix std filesystem
Call Stack (most recent call first):
  config/StdFixes.cmake:203 (make_missing_std_feature_fix)
  CMakeLists.txt:23 (include)

When I check (ls r14/ndk/sources/cxx-stl/llvm-libc++/include/experimental/) ... I see no filesystem. :(

I really wish oglplu2 could reach 1.0, using only C++14 and boost. Otherwise, it leaves too many platforms in the dust.
