osg vcpkg

[Chasikanaft]

How right way install osg with vcpkg for MSbuild (Visual Studio) apps? all osg files in "vcpkg\installed\x64-windows\include\osg" has no extension, so simple: #include <osg/AnimationPath> is not work.

I don't use vcpkg, but it's normal for the OSG header files to not have an extension. C/C++ does not require the header files to have an extension, and no extension should work fine. If your build isn't finding the headers it's probably because the include file search paths are not setup to point to your installed OSG location.

Maybe im not install the OSG environment variables? How do it right for Visual Studio? i think vcpkg do that yourself.

It turns out that I have problems with the visibility of plugins.

Error reading file cessna.osg: read error (Could not find plugin to read objects from file "cessna.osg".)
```	
I tried to put `osgdb_osg.dll` in project directory, in build directory (x64 too), moved plugins from` {VCPKG_PATH}/x64-windows/tools/osgPlugins-3.$.$` to `{VCPKG_PATH}/x64-windows/lib/osgPlugins-3.$.$`, but i have no vision for it.

That sounds like the problem. Here are two solutions to try:

1. Add your OSG bin folder to the windows PATH environment variable. You can do this either by the windows UI or command prompt. The OSG bin folder should contain the main OSG dlls and an osgPlugins folder, for example:
2. Copy the contents of the OSG bin folder to your application's binaries folder. This is the preferred solution for installed applications (i.e to be used by end-users) but not so good for development because it requires duplicating files.

1. Done. nothing happend, also i add env var like OSG_BIN_PATH, OSG_INCLUDE_PATH, OSG_LIB_PATH too.
2. Osg *.dlls copy right into x64 app folder, vcpkg already do that, but not plugins, copy plugins dir make no result.

I Check .exe dll with Dependechies tools, and nothing relust for plugins too. i can try install osg with cmake, but is strange)

Ok im reinstall it from cmd - vcpkg install osg[core,plugins]:x64-windows --recursive and now i have several *.exe files like osgviewer.exe, into {VCPKG dir installed}/windows-x64/tools/osg/. Interesting, but osgviewer.exe work ( some warnings apply, but still executable), before that, im check that .exe with Dependencies tool and miss some dlls like osgViewer.dll, osgGA.dll, osgDB.dll and other wich placed into /bin folder. after that i add /bin folder to the Path env again (as you advised). After this thing i conduct for it, in Dependencies tool so all dll's is found, and *.exe being work.

But simple code like

#include <windows.h>
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>

#include <iostream>



int main(int argc, char **argv)
{
	// use an ArgumentParser object to manage the program arguments.
	osg::ref_ptr<osg::Node> root = osgDB::readNodeFile("cessna.osg");
	osgViewer::Viewer viewer;
	viewer.setSceneData(root.get());

	return viewer.run();
}

again drop the message: Error reading file cessna.osg: read error (Could not find plugin to read objects from file "cessna.osg".)
