Cmake generator file glob9/12/2023 ![]() c.o: in Makefiles) so they have to know the exact list of source files. They all generate per-file rules (not wildcard rules like. Also, one cool thing is the DEPENDS part in the macro also lists the generator script. Any build system (not necessarily CMake, but also GNU autotools etc) has to generate build rules for all files. I also specified INSTALLs for the output files. Here is the directory structure: ROOT - build - CMakeLists.txt mypythonscript.py - subfolder - build - CMakeLists. I chose to use the filename of the output file as the name of the target. You can also set CONFIGUREDEPENDS on a GLOB ed set of files. ![]() A generator may be selected via the cmake -G option, interactively in cmake-gui. CMake has new block scoping commands selectively controlling variables and policies. ![]() The library use an empty file in the root directory of the source package. CMake Use GLOB to generate filelist for install package Patrik Lehmann patrik.lehmann at Thu Aug 11 05:03. Unix Makefiles, Ninja, etc.) The value of this variable should never be modified by project code. while writing a FindXXX.cmake module, I am trying to figure out the version of the library. The macro is more general, and in the foreach, I use it in a specific way. The name of the generator that is being used to generate the build files. macro(add_some_kind_of_target target_name infile outfile)ĬOMMAND my_script.sh -in $ DESTINATION share/sqlite/database/BD) One could create such an add_macro for each command that they use to generate things. Given our situation, you may modify the generated file and see how that goes, then if pleased, you modify the input file.Ī macro called add_something that creates a target. I applied it to one situations where the files are all generated the same way but updating one of the dependencies would cause the whole group of files to be regenerated. When using CMake, make sure that all software that CMakeLists.txt files depend on has been installed, so that a functional Makefile can be generated by CMake. I've used your thing in many places with different files and different commands. CMake uses CMakeLists.txt files to describe project configuration, source files, and dependencies. They were not in the same directory which is why I couldn't get it to work (I think) but either way, the way he's doing seems to be the 'right' way. Just a simple script generates an output file from an input and I couldn't get making the target to cause the script to be called to generate the files. Build, which then runs the CMake generator specified in the project configuration: make, mingw32-make, nmake, or ninja. Oh and as for "can I get that somehow?", the answer seems to be yes, but I was trying that at first and could not for the life of me get it to work. If no CMakeLists.txt file changes when a source is added or removed then the. We do not recommend using GLOB to collect a list of source files from your source tree. ![]() Globbing expressions are similar to regular expressions, but much simpler. This is no real problem as you need to do this only once. Ī target created in the same directory (CMakeLists.txt file) that specifies any output of the custom command as a source file is given a rule to generate the file using the command at build time.Ä«ut goes on to say not to do that if you have multiple targets that depend on one of those files.Äo not list the output in more than one independent target that may build in parallel or the two instances of the rule may conflict (instead use the add_custom_target() command to drive the command and make the other targets depend on that one).įrom that my takeaway is that I will always create a target and not have other targets depend directly on the files. Generate a list of files that match the and store it into the .The documentation seems to say at first that you could do that. That's it that's all for those files and how and when to generate them.Īfter that I should be able to say that some target depends on that file and CMake should know what to do. 'I know it's bad practice' disclaimer: I'm aware that GLOB is discouraged and is bad practice. Any or suggestions help would be greatly appreciated. That's what I wanted to do and what seemed the most straightforward way of doing things: "Hey CMake, here is a group of files and here is the group of files they depend on, and here is how to generate them. file (GLOB VGLOB LISTDIRECTORIES true '') but I'm not quite sure how to filter out the non-directory files and then format it in a way that is acceptable for addsubdirectory. Here is what I am doing: set(THIRDPARTY_INSTALLFOLDER $ "*.In my project I'd like to just have the foo target and not the libfoo_untar target. The DLLs are definitely there before the code reaches the GLOB_RECURSE call. I don't get any result by doing a GLOB_RECURSE on the mainfolder. I want to get all DLLs which are in mainfolder, including sub folders. how to exclude a sub directory from cmake file. I have a folder structure with the following mainfolder/ file(GLOBRECURSE FooSOURCES '.c' '.cpp') Enter the excluded directories here set (excludeDirName '') list (APPEND excludeDirName '/test'). ![]()
