Building and using Log4cplus with CMake

Question

community,

I have the following problem with building and using the Log4cplus library with Embarcadero. First, I download the library from http://sourceforge.net/p/log4cplus/wiki/Home/, then I navigate to a Directory where I want to build my library, and type cmake -G "Borland Makefiles" mypathtotherootomypreviousdownload. It then says, the build files have been written to the current directory. Now I start the MSYS sh.exe and type make. This does also work. I get a bin Folder with various working tests (as exe files) of the library. In this bin folder there is also a dll log4cplusUD.dll. Now I also find in a src folder the corresponding LIB log4cplusUD.lib. I am of course familiar how you can statically link a dynamic library with Embarcadero. But on attempting to compile

#pragma hdrstop
#pragma argsused

#ifdef _WIN32
#include <tchar.h>
#else
  typedef char _TCHAR;
  #define _tmain main
#endif

#include <stdio.h>

#include "log4cplus/logger.h"
#include "log4cplus/consoleappender.h"
#include "log4cplus/loglevel.h"
#include <log4cplus/loggingmacros.h>
#include <iomanip>

using namespace std;
using namespace log4cplus;



 int _tmain(int argc, _TCHAR* argv[]) 
{

    log4cplus::initialize ();
    SharedAppenderPtr append_1(new ConsoleAppender());
    append_1->setName(LOG4CPLUS_TEXT("First"));
    Logger::getRoot().addAppender(append_1);

    Logger root = Logger::getRoot();
    Logger test = Logger::getInstance(LOG4CPLUS_TEXT("test"));

    LOG4CPLUS_DEBUG(root,
                    "This is"
                    << " a reall"
                    << "y long message." << endl
                    << "Just testing it out" << endl
                    << "What do you think?");
    test.setLogLevel(NOT_SET_LOG_LEVEL);
    LOG4CPLUS_DEBUG(test, "This is a bool: " << true);
    LOG4CPLUS_INFO(test, "This is a char: " << 'x');
    LOG4CPLUS_INFO(test, "This is a short: " << static_cast<short>(-100));
    LOG4CPLUS_INFO(test, "This is a unsigned short: "
        << static_cast<unsigned short>(100));
    LOG4CPLUS_INFO(test, "This is a int: " << 1000);
    LOG4CPLUS_INFO(test, "This is a unsigned int: " << 1000u);
    LOG4CPLUS_INFO(test, "This is a long(hex): " << hex << 100000000l);
    LOG4CPLUS_INFO(test, "This is a unsigned long: " << 100000000ul);
    LOG4CPLUS_WARN(test, "This is a float: " << 1.2345f);
    LOG4CPLUS_ERROR(test,
                    "This is a double: "
                    << setprecision(15)
                    << 1.2345234234);
    LOG4CPLUS_FATAL(test,
                    "This is a long double: "
                    << setprecision(15)
                    << 123452342342.25L);
    LOG4CPLUS_WARN(test, "The following message is empty:");
    LOG4CPLUS_WARN(test, "");

    return 0;
}

I get a linker error, not resolved external Symbol log4cplus::Logger::getInstance.

The code above is just one of the tests that compiled and run well, when running make from sh.exe. So what am I doing wrong?

I also tried to link the above main.cpp againts log4cplusUD.lib with the following CMakeLists.txt file

cmake_minimum_required (VERSION 2.6)
project (log4cplustest)

include_directories("C:/Users/fin/Software/log4cplus-1.2.0-rc3/log4cplus-1.2.0-rc3/include")
add_executable(log4cplustest main.cpp)
target_link_libraries(log4cplustest log4cplusUD)

but I get the same Linker error!
