+15.13 CMake build with MIT Kerberos does not work
+
+ Minimum CMake version was bumped in curl 7.71.0 (#5358) Since CMake 3.2
+ try_compile started respecting the CMAKE_EXE_FLAGS.  The code dealing with
+ MIT Kerberos detection sets few variables to potentially weird mix of space,
+ and ;-separated flags. It had to blow up at some point. All the CMake checks
+ that involve compilation are doomed from that point, the configured tree
+ cannot be built.
