+Subject: [PATCH] Fix build without INDI
+
+Without INDI present I get the following error:
+
+"x86_64-pc-linux-gnu-ld: ../lib/libKStarsLib.a(robuststatistics.cpp.o):
+in function `Mathematics::GSLHelpers::gslMedianFromSortedData(
+double const*, unsigned long, unsigned long)':
+.../work/kstars-3.6.5/kstars/auxiliary/gslhelpers.h:306: undefined
+reference to `gsl_stats_median_from_sorted_data'"
+
+That is the case because Mathematics::RobustStatistics is used
+unconditionally, which pulls in gslhelpers and the need to link with
+GSL.
+
+Also drop the duplicate linking of KF5::Notifications, KStarsLib already
+links to it in the NOT ANDROID case.
