Firstly, don't use CMake 2.6.3 for this because it won't work (there is a
bug).  Use 2.6.2 or the latest 2.6.4RC.

set(A_HDRS A/one.h A/two.h A/three.h)
source_group(A FILES ${A_HDRS})
add_executable(HeaderFiles dummy.c ${A_HDRS} EXCLUDE_FROM_ALL)

If that works successfully, you can use the file(GLOB..) command to
determine A_HDRS without listing every header file and then add B_HDRS,
C_HDRS, etc. as needed.

Obviously for dummy.c just use:

int main() { return 0; }
