Summary

0008228: cmake allows creating variables that cannot be dereferenced

Description

Test CMakeLists.txt:

set(!BANG wacky CACHE STRING "" FORCE)
set("var with space" wacky CACHE STRING "" FORCE)

Both of these will create entries in the cache. However, as evidenced by:

message(STATUS "This is !BANG: ${!BANG}")
message(STATUS "This is var with space: ${var with space}")

...such variables cannot be expanded (attempting to do so throws an error). CMake should preferably not allow such variables to be created.

Additional Information

I discovered this while implementing a work-around to bug 8226, basically with the autotools-ism 'if ("!${foo}" MATCHES "bar")'. Therefore I would prefer for such variables to remain invalid :-).
