[CMake] Why SET() not support regular expression ?

[Yang, Y.]

Hi all.

I just use CMake for two week. And I found it's very good tool.
However, I just wonder that why in CMake the SET not support regular
expression.

For example, SET( MY_SRCS mydir/*.c)

if CMake can do this, I don't have to modify the CMakeLists.txt every
time when I add new files to mydir.

Best regards.
