[CMake] How can I add gprof profiler to my CMakeLists.txt?

[Water Lin]

I want to use gprof to analyze my code. So I try to embed the -pg
paramter for g++ in my CMakeLists.txt file.

But after I embeded the -pg to my CMakeLists.txt like this:
---------
add_definitions(-pg -march=pentium4 -msse3 -g)
---------
and I recompile my code. There is no gprof output file.

But when I use command like:
--------
$ g++ -pg ....
--------
to compile my code, gprof will generate a output file gmon.out.

So, how can I enable gprof profiler in my CMakeLists.txt?

Thanks
