[CMake] regular expression help: set a variable for all source file

[Grant Tang]

Hi,

I have a mkdoc target, which is for extracting document information from
all  C/C++
and Python source files. I tried this setting:

SET(MKDOCSRCS
        "@SOURCE_DIR@/subdir1/\\.(C|c|cpp|py)$"
        "@SOURCE_DIR@/subdir2/\\.(C|c|cpp|py)$"
        "@SOURCE_DIR@/subdir3/\\.(C|c|cpp|py)$"
        )
ADD_CUSTOM_TARGET( mkdoc
        DEPENDS ${MKDOCSRCS}
)

But my cmake complain:

CMake Error: can not find file
/home/gtang/EMAN/src/eman/boxer/\.(C|c|cpp|py)$

Tried .c .C .c++ .cc .cpp .cxx .m .M .mm .h .h++ .hm .hpp .hxx .in .txx

Could somebody help me out?

Thanks in advance,
Grant Tang
