Cannot compile using any external libraries (Codeblocks) - c++

Question

I cannot compile any code using external libraries on Code::Blocks.
I tried using the boost lambda example:
#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>
int main()
{
using namespace boost::lambda;
typedef std::istream_iterator<int> in;
std::for_each(
in(std::cin), in(), std::cout << (_1 * 3) << " " );
}
I have a global environment variable set up for the library:

...and I think I set up the build options right.

But my build can't detect the header file:
||=== Build: Debug in boost test (compiler: GNU GCC Compiler) ===|
C:\Documents and Settings\Charlotte\My Documents\wxTest\boost test\boo.cpp|1|fatal error: boost/lambda/lambda.hpp: No such file or directory|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

Unfortunately the boost include path in your first image is cut off. But it looks like
C:\Boost\include\boost-1_62\boost
Right?
That’s most likely incorrect. If you include the lambda header like you did (which is also the usual way to include a boost Header)
#include <boost/lambda/lambda.hpp>
then there needs to exist a file called
C:\Boost\include\boost-1_62\boost\boost\lambda\lambda.hpp
That does not fit the normal Boost directory layout. There is one boost too many in there. Try setting your your global environment Boost path to:
C:\Boost\include\boost-1_62
