[CMake] Default CMAKE_C_FLAGS value by OS

Hello, My question is related to CMAKE_*_FLAGS. I've got a project under linux fedora 24 and, in release mode, this project compiles with the -O2 flag. But when I switched to other platform (ubuntu, fedora 16 - I now this one is quite old but I need to compile on this platform), this default opt

cmake version on fedora 25: 3.6.2 And the corresponding lines in GNU.cmake (there are some differences): # Initial configuration flags. set(CMAKE_${lang}_FLAGS_INIT "") set(CMAKE_${lang}_FLAGS_DEBUG_INIT "-g") set(CMAKE_${lang}_FLAGS_MINSIZEREL_INIT "-Os -DNDEBUG") set(CMAKE_${lang}_FLA

[CMake] cpack logging question

Hi, I am using the cpack variable CPACK_INSTALL_COMMANDS to run an extra command. (First time I do this) I have noticed that whenever the script command fails I get a log with the output in (InstallOtput.log) However when it runs correctly I have no log at all. I have tried to redirect the output

Re: [CMake] Disabling INSTALL target for subdirectory

Use add_subdirectory(... EXCLUDE_FROM_ALL) to prevent anything in there to be installed by default. I had the issue in one project and it did fix it for us. Also, 3rdparty libraries should be tagged like that anyway to be built only when they are used by the main targets. /Florent On Feb 16, 20

Re: [CMake] cmake 3.7.2 centos 7 :: kwsys.testSystemTools (Failed)

Hi Adrian, I'd suggest taking the issue up with the package maintainer. The upstream source for CMake 3.7.2 configures, builds, and passes all tests on EL7 so the problem seems to lie in how the RPM SPEC file is driving the build. -- Chuck Atkins Staff R&D Engineer, Scientific Computing

Thanks a lot for all these informations. I wrote a macro to be sure to replace all the -O3 flags ... # replace_ccxx_flag: replace compilation flags from the compiler command line # flag_orig: the flag to be replace # flag_dest: the new flag value macro(replace_ccxx_flag flag_orig flag_dest) str

Re: [CMake] Disabling INSTALL target for subdirectory

Hi Florent, thank you so much. EXCLUDE_FROM_ALL does indeed have the effect of ignoring any install() invocations from within the subdirectory. I remember stumbling across this option, but from the docs I didn't get the impression that this would affect the installation as well. Maybe the docu
