Dependencies

[OgreTransporter]

Currently, ryu is built as a dependency in the form of a static library. This is not really a problem, unless you also build GEOS statically, too. Then the library ryu is missing on linking against GEOS. Currently I have solved the problem by appending the following to CMakeLists.txt:

if(NOT BUILD_SHARED_LIBS)
  install(TARGETS ryu LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR} ARCHIVE DESTINATION ${CMAKE_INSTALL_LIBDIR} RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR} INCLUDES DESTINATION ${CMAKE_INSTALL_INCLUDEDIR})
endif()

Now the ryu library is installed as well and I can link the target project with GEOS and ryu. But maybe it would make more sense to include the ryu code directly in GEOS.

Does it work as expected if ryu is built as an OBJECT library? (reverting c6abbf9)

The motivation for not including the code directly is #394 . Perhaps it creates more problems than it solves.

I need GEOS to compile spatlite. Currently I get the error message

1>geos_staticd.lib(WKTWriter.obj) : error LNK2019: Reference to unresolved external symbol "geos_d2sfixed_buffered_n" in function ""protected: class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl geos::io::WKTWriter::writeNumber(double)const " (? writeNumber@WKTWriter@io@geos@@IEBA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@N@Z)".
1>D:\SpatiaLite\build\src\Debug\spatialited.dll : fatal error LNK1120: 1 unresolved externals

I have built GEOS as a static library which does not include ryu. Using OBJECT instead of STATIC works for me.

As already written, I have no problem with STATIC if ryu is then installed by CMake and the exported GEOS target then also links against ryu.
