OpenVDBGLFW3Setup
-----------------
Wraps the call the FindPackage ( glfw3 ) for OpenVDB builds. Provides
some extra options for finding the glfw3 installation without polluting
the OpenVDB Binaries cmake.
Use this module by invoking include with the form::
include ( OpenVDBGLFW3Setup )
IMPORTED Targets
^^^^^^^^^^^^^^^^
``glfw``
The glfw3 library target.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``glfw3_FOUND``
True if the system has glfw3 installed.
``glfw3_VERSION``
The version of the glfw3 library which was found.
Hints
^^^^^
The following variables may be provided to tell this module where to look.
``GLFW3_ROOT``
Preferred installation prefix.
``SYSTEM_LIBRARY_PATHS``
Global list of library paths intended to be searched by and find_xxx call
``DISABLE_CMAKE_SEARCH_PATHS``
Disable CMakes default search paths for find_xxx calls in this module
