-Subject: [PATCH] Mark ICU as private linkage (#1366)
-
-* libical-glib: Hide some target options in the installed CMake files
-
-The build paths could be shown in the installed .cmake files, thus
-hide them from there, because they are not needed.
-
-Closes https://github.com/libical/libical/issues/532
-
-* libical: mark ICU linkage as private
-
-There's no need to expose the ICU linkage publically as the .so will
-pull this in itself.
-
-This has a side-effect of removing build/sysroot paths from the installed
-.cmake files.
-
-Closes #532.
