Brad King	0a10958a88	BUG: Fix Unset test on VS 6 ... Visual Studio 6 does not recognize .cc as a C++ extension by default. Simplify the test to be C-only and use a .c extension.	2008-08-30 10:32:52 -04:00
Brad King	33e865c041	ENH: Add unset() command. ... This introduces the unset() command to make it easy to unset CMake variables, environment variables, and CMake cache variables. Previously it was not even possible to unset ENV or CACHE variables (as in completely remove them). Changes based on patch from Philip Lowman. See issue #7507.	2008-08-25 10:31:29 -04:00
