Hi Tim,

could you please run a pwd in your build directory? Also, could you try deleting CMakeCache.txt and re-running cmake?

With "subdirectory" I was asking whether your build directory was a subdirectory of the RDKit root dir or a subdirectory of gmwrapper, because I get that error if I try to run your command from rdkit/Code/JavaWrappers/gmwrapper/build rather than from rdkit/build, as in that case the main CMakeLists.txt file is not sourced.

Cheers,
p.

well, I am running it from a subdirectory - the build subdirectory which is where it has always been run from.
e.g.

mkdir build
cd build
cmake -DPYTHON_EXECUTABLE=/usr/bin/python3  -DRDK_BUILD_INCHI_SUPPORT=ON  -DRDK_BUILD_AVALON_SUPPORT=ON  -DRDK_BUILD_PYTHON_WRAPPERS=ON  -DRDK_BUILD_SWIG_WRAPPERS=ON ..

    Hi Tim,

    downloadAndCheckMD5 is a function defined in
    Code/cmake/Modules/RDKitUtils.cmake, which is included by the main
    CMakeLists.txt file and then is available to all children
    CMakeLists.txt files.

    From the line number where the error occurs

    $ grep -n downloadAndCheckMD5 `find . -name CMakeLists.txt`
    ./Code/JavaWrappers/gmwrapper/CMakeLists.txt:21:
    downloadAndCheckMD5(${JUNIT_URL} "${RDKit_JavaLibDir}/junit.jar"
    ${JUNIT_MD5SUM})

    it looks like you might be running cmake in a subdirectory rather
    than in the RDKit root directory.

    HTH, cheers

    $ cmake --version
    cmake version 3.16.3
    Has anything changed with cmake recently?
