Thanks, Eric. I had plans for adding find_library. I have seen a fair amount about how this is more idiomatic but little about what the disadvantages are in the short run of using an environment variable directly while building up the system. Perhaps I chose a wrong incremental pathway to getting the project up and running.

Normally you use find_library, file_path, etc... in order to discover the path, lib etc... you need then you use CMake variable (and not env var) in your CMakeLists.txt The process of searching third party library and tools is usually bundled in a separate cmake file call a "FindXXX.cmake" file. This file can then be loaded using the find_package CMake command. If you search the web a little bit you'll soon discover that others already crafted a FindNetCDF.cmake script. Here is the first I get with my search: http://gmtrac.soest.hawaii.edu/projects/gmt/repository/revisions/10027/entry/trunk/cmake/modules/FindNETCDF.cmake I suggest you chose a CMake tutorial: http://www.cmake.org/Wiki/CMake#Tutorials and read it thoroughly. No offense but your questions and answers indicates you lack some basic CMake knowlegde that may lead you to misuse CMake and/or get unexpected behavior/error due to misunderstanding. Taking the time to read at least one tutorial will save you time in the future. -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
