+Subject: [PATCH] CMakeLists.txt: fix linking
+
+- Replaced legacy `LINK_PUBLIC` and `LINK_PRIVATE` with plain `PUBLIC`
+  and `PRIVATE` keywords. Ref:
+
+  https://cmake.org/cmake/help/latest/command/target_link_libraries.html#libraries-for-a-target-and-or-its-dependents-legacy
+
+- Changed linking from PUBLIC to PRIVATE to prevent GLEW dependencies
+  from spillng to the outside world (and being injected into the CMake
+  targets), which is causing build failures on Debian:
+
+  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1136422
+
+- Fixed linking of glewinfo and visualinfo.
