[CMake] Regular Expression weirdness (2.6 & 2.8RC3)

[Marcel Loose]

Hi Luis,

The way I'm reading the globbing expression -- which is not identical to
a regex, BTW -- the output makes perfect sense.

In HDR1 you collect all filenames that start with 'Spatial/csp'; then
contain zero or more wildcard characters; then the last character before
the dot should *not* be any of the characters 'c', 'o', 'n', 'f', 'i',
or 'g'; finally the name should end in '.h'.

So, HDR1 does not contain cspacedef.h because the last character before
the '.h' is an 'f', which is one of the "forbidden" characters in the
glob expression.

HTH,
Marcel Loose.
