The reason for this: the configure script compiles the following code:

#include <log4cpp/Category.hh>
#include <iostream>
int main() { std::cout << 1 << '\t' << 0; return 0; }

in order to check that <log4cpp/Category.hh> exists.
But this code still requires -llog4cpp:

/tmp/cc41MUW4.o: In function `__static_initialization_and_destruction_0(int, int)':
2.cpp:(.text+0x5b): undefined reference to `log4cpp::Appender::AppenderMapStorageInitializer::AppenderMapStorageInitializer()'
2.cpp:(.text+0x70): undefined reference to `log4cpp::Appender::AppenderMapStorageInitializer::~AppenderMapStorageInitializer()'
collect2: error: ld returned 1 exit status

As the configure script first searches for the header and only then for library
there appears to be no way to fix this apart from searching for some other
header that doesn't require linking the library (if that exists).
