Building using cmake is not working

[mariuszbarczak]

When trying to build the project using cmake, I've got the following error:

bash: line 1: /home/mariusz/git/libbpf-bootstrap/examples/c/../../tools/bpftool: No such file or directory
make[2]: *** [CMakeFiles/bootstrap.dir/build.make:74: bootstrap.skel.h] Error 127
make[2]: *** Deleting file 'bootstrap.skel.h'
make[1]: *** [CMakeFiles/Makefile2:145: CMakeFiles/bootstrap.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

I added ExternalProject_Add in examples/c/CMakeLists.txt for bpftool, it started working. Is it acceptable?

Greeting,
I think it's because the path to bpftool executable is not updated in the CMakeList.txt.
May I make a PR to fix this, or you prefer to do it by yourself?

@danobi can you please take a look if you get a chance? But either way, @JackyYin, please go ahead and submit your fix, thank you!

[danobi]

The submitted fix lgtm. Sorry, not checking my libbpf email folder that often.
