[CMake] File names with unbalanced square brackets

[CHEVRIER, Marc]

I think you can resolve your problem with the following syntax for foreach command:
Foreach (FILE IN LISTS FILES)

In this case the list is not expanded in your source so square brackets is no longer interpreted…

Hi Allen.

I'm not sure whether it's documented, but CMake interprets square brackets as escaping the semi-colon character (which means a semi-colon in square brackets will not work as a list item separator). You will probably have to translate the file names for CMake processing by replacing [ and ] with a different string, and replacing it back just before use outside of CMake.

I inherited a set of files with somewhat unusual file names. In particular, there were a couple of files whose names included a single square bracket character. I processed these files with the file( GLOB ...) command and then iterated over the resulting list with foreach. However, the foreach command does not seem to break the resulting list apart correctly. To make this concrete, I have a directory with files named "a", "b[", and "c". file( GLOB FILES "*" ) returns the list:

/home/allen/test/b[;/home/allen/test/c;/home/allen/test/a

However,

foreach( FILE ${FILES} )
  message( ${FILE} )
endforeach()

just prints the same thing. That is, foreach does not split FILES into separate pieces. If I rename "b[" to "b]" I see the same behavior. If I rename "b[" to "b[]" (or even "b]["), then foreach successfully splits FILES into the individual file names.

I'm using CMake 3.3.2. I see the same thing on linux and windows.

Thanks,
Allen
