9/26/2023 0 Comments Cmake generator file globIs their a clean way to retrieve a list containing only the relative path. As an alternative to explicitly building up a list of source files in a variable, some developers instead choose to let CMake find the source files and generate the contents of that variable automatically with the file (GLOBRECURSE. For example : FILE (GLOB SRCFILES Test.cxx Test.cpp Test.c) Here, SRCFILES will contain all the file i requested with their full path. Game/knuckles/CMakeLists.txt add_custom_command(ĬOMMAND "py" "$ DESTINATION ". in the 2.2 version book, but im quite a beginner regarding CMake ) Id like to retrieve the relative path of a list of files. VS2022 17.3.4 (i tried with commandline too so i guess it wouldnât be matter though).Iâm using cmake with visual studio 2022 integrated environment. I am using this line in my cmake: FILE(GLOBRECURSE ALLLibCPPSRCS src/Library/. I want to write a cmake in a way that it add all of them to project without asking to writ them separately. I googled about it a lot, but it seems unusual for people.Īll the explanation tells me that they donât seems experiencing the issue.Īnd it seems âtouchâ is necessary to pick âdependsâ option is it supposed to be necessary? I have a library with several source files under several directories. For now, I use file(GLOBRECURSE sourcelist '.cpp' '.h') in order to automatically add new files to project. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake is part of a family of tools designed to build, test and package software. So a library file(lib.cpp) that including it recompiled. CMake is a cross-platform, open-source build system. Generate an output file for each build configuration supported by the current CMake Generator. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. ![]() When I changed the template file(DataTableSchema.h) and try build, ninja only executes custom command and not build a library.Īnd next time I command build with ninja, ninja detects that generated header file(datatable.hpp) has been modified, We do not recommend using GLOB to collect a list of source files from your source tree. Generate a list of files that match the and store it.This command is invoked by a project in the. CMake provides the install command to specify how a project is to be installed. This allows it to be distributed in a clean form and isolates users from the details of the build process. Do not list the output in more than one independent target that may build in parallel. A relative path (after evaluating generator expressions) is treated with. Software is typically installed into a directory separate from the source and build trees. I think that Ninja sees that the file has not changed and does not. While using Ninja the generator runs at every build (as described above) without rebuilding every time. Not globbing causes you to lose the CMake logic amongst huge lists of files. This is a big plus if you have lots of files. ![]() Your CMakeLists.txt file will be shorter. ![]() This is not too big of a deal because it is really fast, but I hopped there was a better way to do it. Original answer: The advantages to globbing are: It's easy to add new files as they are only listed in one place: on disk. h files to the project file ( GLOB SOURCES '. So basically the generator expressions are for everything only the generator could know: The name and path of target outputs (mainly when cross. A 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. The generator runs every time, even if the input files did not change. Listing A.5 An example CMake script for generating simple application projects for. CMake does first parse the CMakeLists.txt files in your project - named 'Configuration Phase' - and then it generates your build environment - named 'Generation Phase'.
