Subject: [PATCH] build: cmake 3.1 compatibility

* fix problem with REMOVE_DUPLICATES on undefined lists
* since 3.1 file(GLOB FILEPATHS RELATIVE .. returns single / instead of // as
  previously - necessary adoptions for regex and matches done. Should
	work with all cmake versions.

Tested with 3.1.0-rc3
