Xcode adding new library - c++

Question

I ran into a problem I just can't fix. The problem is Im trying to add a new library to xcode and never did it before. I don't really now if the problem is library related or me adding a new library to xcode.
The Library Im trying to add is tidylib (tidy-html5).
#include <tidy.h>
#include <tidybuffio.h>
#include <stdio.h>
#include <errno.h>
int main(int argc, char **argv )
{
const char* input = "<title>Foo</title><p>Foo!";
TidyBuffer output = {0};
TidyBuffer errbuf = {0};
int rc = -1;
Bool ok;
TidyDoc tdoc = tidyCreate(); // Initialize "document"
printf( "Tidying:\t%s\n", input );
ok = tidyOptSetBool( tdoc, TidyXhtmlOut, yes ); // Convert to XHTML
if ( ok )
rc = tidySetErrorBuffer( tdoc, &errbuf ); // Capture diagnostics
if ( rc >= 0 )
rc = tidyParseString( tdoc, input ); // Parse the input
if ( rc >= 0 )
rc = tidyCleanAndRepair( tdoc ); // Tidy it up!
if ( rc >= 0 )
rc = tidyRunDiagnostics( tdoc ); // Kvetch
if ( rc > 1 ) // If error, force output.
rc = ( tidyOptSetBool(tdoc, TidyForceOutput, yes) ? rc : -1 );
if ( rc >= 0 )
rc = tidySaveBuffer( tdoc, &output ); // Pretty Print
if ( rc >= 0 )
{
if ( rc > 0 )
printf( "\nDiagnostics:\n\n%s", errbuf.bp );
printf( "\nAnd here is the result:\n\n%s", output.bp );
}
else
printf( "A severe error (%d) occurred.\n", rc );
tidyBufFree( &output );
tidyBufFree( &errbuf );
tidyRelease( tdoc );
return rc;
}
My problem is that I get the following error all the time and I just can't fix it:
Undefined symbols for architecture x86_64:

_main in main.o
"_tidyCleanAndRepair", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
What I did?
I set up the header search path to "/usr/local/Cellar/tidy-html5/5.6.0/include/"
I set up the library search path to "/usr/local/Cellar/tidy-html5/5.6.0/lib/"
I also tried to set other link flags to "-ltidylib"
System?
MacOS High Sierra 10.13.4
XCode 9.4.1
Solution
You have to use "-ltidy" instead of "-ltidylib" under other Other Linker Flags

Select your target (typically the app you're building) and click on the Build Phases tab. Build phases are the different steps needed for building, such as checking dependencies, compiling, copying resources, etc. One of them is "Link Binary with Libraries", and it includes a list of libraries and frameworks that your project should link. Click on the + button to add a new item to the list, and choose the library you want to add. Then build.
