This script needs granted permissions; so, it's included in a suid
binary. Once i talked about a security key for this binary.
The security key would be generated during the compilation of the
application in a way that only those binaries built *together* with the
suid binary will know it.
First of all, i have to deal with the add_custom_command() function of
CMake, in order to control the preference of the targets.
The first step should be to generate this key, before all the executables.

Cheers,

 Aitor.
