Re: [CMake] Changing the the current generator in CMake GUI
Well, CMAKE is the thing that is conflating this idea of a "generator" (which is clearly a concept in CMAKE's own domain of "build configuration generator") with the idea of "platform" or "architecture" (which is a concept in the domain of certain kinds of build tools, such as a C compiler.) It would be healthier if platform/arch were broken out as a separate item in CMAKE, i.e. CMAKE recognizes that some build tools have this concept, but is (possibly) agnostic about how it is represented. I assume that it is not really possible to do so in the config files that drive CMAKE at present, only because I have never seen it done and did not find it when I went looking. Instead, that information is scattered across several files in the CMakeFiles folder. Thank you for the hints and examples about using batch files. I may try to implement that scheme for building support libraries that come dependent on CMake. But I don't believe that I will ever use CMake for any product I am in control of, mainly because I have seen what an unmaintainable mess it creates for project files. And at least partly as a result, since there is no direct comprehension on the part of the developer/maintainer as to the project file structure, it becomes impossible to adequately manage that structure, so making large-scale improvements is nearly impossible without starting over from scratch. In addition, the build process becomes way inefficient. For example, once when I was really at loose ends due to a management blow-up, I reworked the build system for HDF5 on Visual Studio so it had "normal" project files that could be used to build for various platforms and configurations. The resulting build time was cut by a factor of 5, plus it became much easier (for me anyways) to be able to do things like change the output file names based on platform, something I have so far found impossible to do with CMake. [Once again, it really has no concept of this.] I would do the same thing for OpenCV, but it is ten times worse than HDF5 in this regard. For instance, apparently project files are modified as part of the MSVS build process, so that Visual Studio always complains about project files needing to be reloaded after a build. This is a recipe for mysterious bugs that you will never be able to fix. I have created/maintained multi-platform projects, and I find that the effort needed to produce efficient, readable makefiles for each platform is worth it. Once done, I can change the platform or the library type or similar parameters by changing one switch in each platform's makefile. Plus there are fewer gotchas at runtime, as not querying the build environment for every build ensures more consistent behavior in the binaries I am going to distribute. Thanks again to all for the comments on this thread. It is good to know that development continues on this tool. At some point, it may become more interesting for me.

Absolutely, that's why this is a single generator and is generated once. Unfortunately, the different settings limitation of this solution is rather...limiting. It would be really nice if this could be made to work with different settings for the different CPU architectures (mostly just library paths for my past uses), just like native Visual Studio, XCode, Eclipse, and Android Studio projects do, but that would apparently be a very major change. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

Re: [CMake] ExternalProject_Add support for git clone -o option
To elaborate on my reply: I do indeed interact with the repository after it's cloned (as per my previous email). With regards to implementation, I have implemented it such that the git remote name is only involved if git is chosen as the source of choice, in much the same manner as the git_tag implementation. My implementation makes the git remote name completely optional and defaults to "origin".

The VC project files produced by the CMAKE system for OpenCV use absolute paths and use them throughout the project files, rather than defining things at top-level and then using predetermined macros like $(TargetDir) and $(TargetName), to say nothing of conveniences like $(PlatformTarget). I don't really know if that is inherent in how CMAKE generates the project files or if there is a way to produce more easily maintainable project files, but every time I have to utilize a project that involves CMAKE I cringe because of the ugly project files it produces. The makefiles produced have been the same way, with the same absolute paths occurring over and over in the file. I do not like this, as it makes the project files/makefiles difficult to debug or maintain. Having expressed this dislike here, I feel much better and will probably not think about this much in the future, up until the point I have to update to a new version of a library such as OpenCV or HDF5. Then I will cringe; pick through all of the settings and generate the makefiles/project files again; debug the results for a day or so until the builds actually, you know, work; and then do my little edit-and-regenerate trick to build for the other architecture. Because the design of CMAKE does not recognize that the results of "try-compile" tests are orthogonal to settings like "build module A" or "build shared libraries", so that the latter should not depend upon the former. -- View this message in context: http://cmake.3232098.n2.nabble.com/Changing-the-the-current-generator-in-CMake-GUI-tp7587876p7592499.html Sent from the CMake mailing list archive at Nabble.com. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

See the documentation here: https://cmake.org/cmake/help/v3.4/module/CPackRPM.html All of this should be done before calling: include(CPack) Hope this helps.

Re: [CMake] How to on multiple RPM packages
Hm I've accidentally dropped cmake mailing list when replying before... Sorry about that. > Im using "bin" and "devel" as component names. I tried next with upper and > lower case in the properties but no difference. > it's about what you see in the RPM header using "rpm -qlip name.rpm" ... Component name changing patch was already applied in git and will be available in next CMake release. Until then you could patch your CPackRPM.cmake file (comes with CMake installation) with this patch: https://cmake.org/gitweb?p=cmake.git;a=commit;h=c926efa > a) Also it is documented CPACK_RPM_DEVEL_PACKAGE_DESCRIPTION has no > effect I always get "This is an installer created using CPack > (https://cmake.org). No additional installation instructions provided." > b) Same for summary. I always get "NGSelector built using CMake" It's possible that you are using an older version of CPack that doesn't support this per component feature. This was introduced in CPack version 3.2. Before only non component versions of description of summary were supported. > c) I cannot specify different groups like "Application" and "Library"? Fix is the same patch as for name. > d) Can I get rid of the "-bin" in the RPM file name? Not at the moment... There are pending bug reports for this. You could however use above patch to change package name and rename the file name manually after generation.

Re: [CMake] How to on multiple RPM packages
Hi Thomas, CPack RPM may generate several packages at once if you define COMPONENTS in your project. The behavior of CPackRPM w.r.t. COMPONENT packaging depends on Some CPack COMPONENT generic variables, namelly: CPACK_RPM_COMPONENT_INSTALL --> this one must be set to ON CPACK_COMPONENTS_* variables see: https://cmake.org/cmake/help/v3.4/module/CPackComponent.html The bunch of RPM specific variables CPACK_RPM__* variables see https://cmake.org/cmake/help/v3.4/module/CPackRPM.html More references (some may be outdated) there: https://cmake.org/Wiki/CMake:Component_Install_With_CPack https://cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29 http://cmake.3232098.n2.nabble.com/CPack-RPM-with-COMPONENTS-packaging-td7583729.html 2016-01-15 9:05 GMT+01:00 Thomas Lehmann : > > Hi, > > We are currently looking forward to migrate to CMake and > we are struggling a bit with cpack. > > The first project we migrate provides a executable binary but also > a library and its headers. > > I do not find an example on how to provide separate RPM's > for them; one for the binary and one for the headers+library. > The required results (rough example): > > - foo-1.2.3.4-1.x86_64.rpm > - libfoo-1.2.3.4-1.x86.64.rpm > > Anybody who can help us with this? > > Regards, > Thomas > > -- > > Powered by www.kitware.com > > Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ > > Kitware offers various services to support the CMake community.

[CMake] How to on multiple RPM packages
Hi, We are currently looking forward to migrate to CMake and we are struggling a bit with cpack. The first project we migrate provides a executable binary but also a library and its headers. I do not find an example on how to provide separate RPM's for them; one for the binary and one for the headers+library. The required results (rough example): - foo-1.2.3.4-1.x86_64.rpm - libfoo-1.2.3.4-1.x86.64.rpm Anybody who can help us with this?
