Package: cmake Version: 3.2.2-2+b1 Severity: normal Hi,
recently I saw something weird in the log and I had to investigate. Background: I am partial upstream on icewm (the fork version) and I added a CMake based build system to it a couple of months ago. IIRC I was using cmake 3.0 or 3.1 at that time. Later, during the DebConf, the weird effects came up. I didn't notice first because my travel laptop had an older cmake version but the build daemons caught it. Here is an example: https://buildd.debian.org/status/fetch.php?pkg=icewm&arch=powerpc&ver=1.3.8%2Bgithubmod%2B20150818%2Bad97152-1&stamp=1439893905 Two things are wrong there: - the compiler identification reports crap - find_library check fails on libSM and libICE Both libs are in the multiarch lib directory... I discovered this by looking at strace output, only the regular lib directories were searched. This gave me a clue that it's somehow path/variables related and by removing the command arguments, I identified -DPREFIX as the culprit. I also found out that export CXX=g++-4.9 CC=gcc-4.9 makes the problem go away, so this might be GCC5 related. On the other hand, I modified the upstream source now to use another name instead of PREFIX and it also makes the problem disappear. (after some pondering, I decided to use the "popular" one, CMAKE_INSTALL_PREFIX) Hope that were enough clues for reproduction and fixing.
