Building with OpenVDB #8

Closed mboisson closed 4 years ago

mboisson commented 4 years ago

Hi, I have OpenVDB installed, but CMake won't find it : 

CMake Warning at vdb_util/CMakeLists.txt:41 (find_package):
  By not providing "FindOpenVDB.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenVDB", but
  CMake did not find one.

  Could not find a package configuration file provided by "OpenVDB"
  (requested version 7.0.0) with any of the following names:

    OpenVDBConfig.cmake
    openvdb-config.cmake

  Add the installation prefix of "OpenVDB" to CMAKE_PREFIX_PATH or set
  "OpenVDB_DIR" to a directory containing one of the above files.  If
  "OpenVDB" provides a separate development package or SDK, be sure it has
  been installed.

What do I need to give as argument for CMake to find it ?

Hi,

your version of OpenVDB seems to be installed into a lib64 subdirectory. Our CMakeLists.txt file in vdb_util assumes a subdirectory called lib. Could you try changing this in vdb_util/CMakeLists.txt:

  list(APPEND CMAKE_MODULE_PATH ${OpenVDB_ROOT}/lib/cmake/OpenVDB)

to

  list(APPEND CMAKE_MODULE_PATH ${OpenVDB_ROOT}/lib64/cmake/OpenVDB)

Thanks. I added a symlink from lib to lib64 and that got it detected correctly.
