Edit for Mac: runtime/cpp_stl/CMakeLists.txt

[idoimaging]

Hi,

On the Mac I was not able to link the symbols iconv, iconv_open and iconv_close called in runtime/cpp_stl/kaitaistream.cpp. This was due to the find_library ICONV_LIBRARIES line in CMakeLists.txt looking for libiconv, when on the Mac it needs to look for iconv. The same line looks for c so it was finding /usr/lib/libc and not /usr/lib/libiconv, which is installed. libc of course can not resolve the iconv symbols. I took out c and added iconv.
I also added two lines to install the headers in a kaitai subdirectory (as the generated C++ files look for kaitai/kaitaistruct.h). One line to add PUBLIC_HEADER to set_target_properties, and one line in the install target to install the two .h files.
Tested on Mac and Linux but not Windows.

I'm merging this in, but please note that this CMakeLists.txt is effectively unmaintained and not really supported. See also #22 for gory details.

Got it, thanks. I should have read PR 22 earlier. I made only a few changes and I hope it will help someone else with C++/libiconv issues especially on the Mac.
