OpenVDBUtils.cmake
------------------
A utility CMake file which provides helper functions for configuring an
OpenVDB installation.
Use this module by invoking include with the form::
include ( OpenVDBUtils )
The following functions are provided:
``OPENVDB_VERSION_FROM_HEADER``
OPENVDB_VERSION_FROM_HEADER ( <header_path>
VERSION [<version>]
MAJOR [<version>]
MINOR [<version>]
PATCH [<version>] )
Parse the provided version file to retrieve the current OpenVDB
version information. The file is expected to be a version.h file
as found in the following path of an OpenVDB repository:
openvdb/version.h
If the file does not exist, variables are unmodified.
``OPENVDB_ABI_VERSION_FROM_PRINT``
OPENVDB_ABI_VERSION_FROM_PRINT ( <vdb_print>
[QUIET]
ABI [<version>] )
Retrieve the ABI version that an installation of OpenVDB was compiled
for using the provided vdb_print binary. Parses the result of:
vdb_print --version
If the binary does not exist or fails to launch, variables are
unmodified.
