Summary0014571: CMake does not validate cache entries given on the command line
DescriptionTypically you set a cache entry like this:

cmake -DMYFLAG:string=ON

However, cmake also accepts this degenerate case:

cmake -D:string=ON

When called like this I got very strange build failures:

[ 32%] Building C object progs/bkz/prog/CMakeFiles/bkz.dir/bkz.c.o
cd /import/build/magnus/rembuild/boks/redhat-6.0/progs/bkz/prog && /usr/bin/cc -I/import/build/magnus/rembuild/boks/redhat-6.0/BUILD/include -o CMakeFiles/bkz.dir/bkz.c.o -c /import/build/mj/boks-sources/boks/progs/bkz/prog/bkz.c
Linking C executable ONbkz

Note that when linking, bkz had received the prefix "ON" which shouldn't be there, and caused subsequent errors.

(CMake got called with bad input like this due to a bug in our build scripts, where a variable was sometimes not set. This was very hard to track down. If CMake had validated the input, this would have been much easier to find.)
