[CMake] String error Cmake

[Mauricio Klein]

The complete error is the following:

----------------------------
CMakeFiles/MonitoraITSchedulerAgent.dir/SourceCode/src/Executor.cpp.o: In
function `Executor::execute(Service*, unsigned int)':
Executor.cpp:(.text+0x8c): undefined reference to
`Executor::runCommand(char const*, unsigned int, std::basic_string<char,
std::char_traits<char>, std::allocator<char> >&)'
CMakeFiles/MonitoraITSchedulerAgent.dir/SourceCode/src/ServiceProvider.cpp.o:
In function `ServiceProvider::sendDiscovery()':
ServiceProvider.cpp:(.text+0x9b6): undefined reference to
`Executor::runCommand(char const*, unsigned int, std::basic_string<char,
std::char_traits<char>, std::allocator<char> >&)'
collect2: ld returned 1 exit status
make[2]: *** [MonitoraITSchedulerAgent] Error 1
make[1]: *** [CMakeFiles/MonitoraITSchedulerAgent.dir/all] Error 2
make: *** [all] Error 2
----------------------------

The function header that is generating the error is:

----------------------------
int runCommand(const char* command, unsigned int timeout, string& output);
----------------------------

I've already included "<string>" and declared "using namespace std".

Thanks for any reply!
