How can I use cmake to do the same thing?
Add your -g flag to CMAKE_CXX_FLAGS or I think you can use
ADD_DEFINITIONS("-g").
It would be better to edit the CMAKE_CXX_FLAGS_DEBUG cache variable.
add_definitions(-g) is bad for a several reasons...
It will break for compilers that do not accept -g, it will add -g to
release and optimized builds.

hello, I use CMAKE_CXX_FLAGS_DEBUG like this:
cmake -DCMAKE_CXX_FLAGS_DEBUG="-g" CMAKE_INSTALL_PREFIX=/usr ..
But the result is:
This GDB was configured as "i486-linux-gnu"...
(gdb) b main
Breakpoint 1 at 0x80487b3
(gdb) r
Starting program: /home/kermit/Project/FreeRecite/build/bin/FreeRecite-core
Breakpoint 1, 0x080487b3 in main ()
Current language: auto; currently asm
(gdb) n
Single stepping until exit from function main,
which has no line number information.
It is obvious that the debug information haven't been included. Why?
Is there something wrong when I use the cmake command?
Thanks.
Kermit
