How can I import osgVolume from OSG?

[jepessen]

I want to use the osgVolume library from OpenSceneGraph, in Windows.
The library was installed correctly, but I cannot find the library. The full path of the library is

E:\Projects\project\build\Debug\vcpkg_installed\x64-windows\lib

And I'm trying to find it with:

find_library (OSGVOLUME_RELEASE_LIB osgVolume  PATHS ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/lib       NO_DEFAULT_PATH)

But the content of OSGVOLUME_RELEASE_LIB is (printed with a message):

E:/Projects/project/build/Debug/vcpkg_installed/x64-windows/include

If I try to find the debug library, it works:

find_library (OSGVOLUME_DEBUG_LIB   osgVolumed PATHS ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/debug/lib NO_DEFAULT_PATH)
OSGVOLUME_DEBUG_LIB    is E:/Projects/project/build/Debug/vcpkg_installed/x64-windows/debug/lib/osgVolumed.lib

The _VCPKG_INSTALLED_DIR and VCPKG_TARGET_TRIPLET variables are correct, and ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET} is

E:/Projects/project/build/Debug/vcpkg_installed/x64-windows

In include dir there's a header folder named osgVolume, maybe it can cause the confusion.

How can I find the correct file?

Why don't you use built-in module?

And I'm trying to find it with:

find_library (OSGVOLUME_RELEASE_LIB osgVolume  PATHS ${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/lib       NO_DEFAULT_PATH)

But the content of OSGVOLUME_RELEASE_LIB is (printed with a message):

E:/Projects/project/build/Debug/vcpkg_installed/x64-windows/include

I would take this as indication that the cache variable OSGVOLUME_RELEASE_LIB is already set before calling find_library. Check if you use in OSGVOLUME_RELEASE_LIB in parameters to cmake or in another, earlier call.
