Compiling C++ code with NetCDF libraries: "undefined reference"

Compiling C++ code with NetCDF libraries: "undefined reference"
Hi!
I am trying to compile a C++ code with cmake and gcc on Ubuntu. The code uses NetCDF4 libraries. I specify the path to these libraries as follows:
-I/usr/local/include -L/usr/local/lib -lnetcdf -lnetcdf_c++4
"ccmake" and "cmake" work fine. After typing "make" I receive the error message:
Linking CXX executable guess
CMakeFiles/guess.dir/modules/guessio_daily_netCDF.cpp.o: In function `getYearlyRecord(Coord, double*, xtring, int)':
guessio_daily_netCDF.cpp
.text+0x8309): undefined reference to `netCDF::NcFile::NcFile(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, netCDF::NcFile::FileMode)'
(...)
I receive the same message when I specify the path to my NetCDF4 libraries with a not-existing path (e.g. -I/blablabla/include ...). As I understand, the linker does not find my NetCDF libraries, correct? Do you have any suggestions on how to solve this problem? In case it helps, below I include the paths of all my netcdf libraries. The libraries were built with the same compiler (gcc). Thank you very much in advance!
Cheers,
Chris
