I suppose it could, i wasn't aware of one at the time. The current cmake code primarily works via `find_package(JNI_REQUIRED)`. That sets up all the things regarding java which may give trouble. The rest is looking for hdfs.h and the related shared library which is very boilerplate and all paths should be externally providable. I have indeed only tested this on debian and ubuntu systems running cloudera hadoop and wouldn't be surprised if the build step didn't work elsewhere.\r\n\r\nThe linked cmake package in dmlc-core  certainly looks more robust, converting to it would be a reasonable goal imo."}}
