Summary0013140: CMake does not reject unsupported logical target names
DescriptionI am migrating a project from Visual Studio to CMake that contains several executables with spaces in their names. While the project builds fine when generating Visual Studio project files, it fails to build when using NMake due to invalid makefiles.
Steps To Reproduce1. Create a project with an executable target containing a space.
2. Use CMake to create NMake files for the build.
3. Attempt to build.
Additional InformationIt appears that the problem is caused by attempting to use the target name in makefile macro names without replacing the space. For example if you have a target named "Spiffy Command-Line Tool", build.make will contain a macro named "Spiffy Command__Line Tool_OBJECTS".

Given that the hyphen is replaced by a double underscore, it looks like CMake already does some name-mangling, it just doesn't handle spaces, currently.

We don't intend to support code like

 add_executable("exe name with spaces" ...)

directly. The bug is that this is not rejected with a nice error. We'll need to add a CMake Policy to restrict logical target names to some supported set.

Meanwhile if you want an executable with a space in its name then create it like this:

 add_executable(exe_name_with_spaces ...)
 set_property(TARGET exe_name_with_spaces PROPERTY OUTPUT_NAME "exe name with spaces")
