BUG: Skip a command if its arguments fail to parse

Browse Source 
If the arguments to a command fail to parse correctly due to a syntax
error, the command should not be invoked.  This avoids problems created
by processing of commands with bad arguments.  Even though the build
system will not be generated, the command may affect files on disk that
persist across CMake runs.
