+Subject: [PATCH] Fix building outside git repository
+
+Currently when building the project on a machine that has git installed,
+but the source is not inside a git repository cmake fails with the
+following error.
+
+	CMake Error at CMakeLists.txt:35 (if):
+	  if given arguments:
+
+		"STREQUAL" "/home/lars/libad9361-iio"
+
+This is due to LIBAD9361_GIT_REPO variable being empty. In order to handle
+empty variables in CMake in a string comparison they need to be
+encapsulated in quotes.
