![]() ![]() This approach would be easier to use with a built-in cmake function, but Iâm asking about coding best practice. 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. I wasnât sure whether I should post this on the code or development forum. Original answer: The advantages to globbing are: It's easy to add new files as they are only listed in one place: on disk. This would be easy to maintain with a git hook or something. This would allow you to do something like cd src ls *.cpp > filelist.txt cd. 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. The list of source files is not some special entity, it is just a list of arguments to a CMake command. Its initial value is taken from the calling process environment. ![]() In case of Linux/macOS it can be done by simply touch ing the CMakeLists.txt, not sure about Windows. Get_filename_component(fullpath_filelist "$" PARENT_SCOPE) I have a library with several source files under several directories. FILTER is another option which could be more convenient in some cases: list (FILTER REGEX ) This line excludes every item ending with the required filename: list (FILTER libsrcs EXCLUDE REGEX '.b44ExpLogTable. You need to bump it by either editing the source file list by hand or otherwise modifying CMakeLists.txt to force CMake to re-run GLOB.Something like cmake_minimum_required(VERSION 3.4)įunction(read_filelist filelist_file return_var) Is their a clean way to retrieve a list containing only the relative path. For example : FILE (GLOB SRCFILES Test.cxx Test.cpp Test.c) Here, SRCFILES will contain all the file i requested with their full path. Instead of maintaining the list of files in the cmake code, would storing the file list in a newline separated file be reasonable? 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. Otherwise, the must evaluate to an unique name for each configuration.Multiple configurations may generate the same output file only if the generated content is identical. Use generator expressions such as to specify a configuration-specific output file name.When I changed the template file (DataTableSchema.h) and try build, ninja only executes custom command and not build a library. This can be tedious to maintain, especially at the start of a project when the source files are changing more often, and it makes maintaining support for multiple build systems more difficult because the filelist is maintained in cmake code. Specify the output file name to generate. Code os:windows, gen:ninja hihig2001 (JihwanKim) October 6, 2022, 4:05pm 1 Hi, Iâm trying to generate a header file during build. chosen generators, the path of the build tree, and more especially when we have more than one way. Typically, people recommend to hardcode the list of files into a cmake variable. CMake uses quite a few files to manage its projects. Process the given cmake file as a script written in the CMake language. In that case the variable substitution will be performed by CMake itself before it passes the string to the command.Iâve commonly seen advice to avoid globbing for files because cmake wonât automatically rerun if a file is added. A makefile generator is responsible for generating a particular build system. If you want to expand variables, you could firstly expands them with command configure_file into intermediate file, and then expand generator expressions in that file using file(GENERATE): # -> Ĭonfigure_file($/output.xml CONTENT Evaluate generator expressions from the input content to produce the output content. But it's a bit of a pity to discard your 'find all files in a specific category' script, included by all your apps, and start enumerating every file individually. to the fact that CMake is a build system generator the resulting build configuration (for make). obj extension' and suddenly it starts including C++ object files as well. Generator expressions are evaluated during build system generation to produce. Source directory layout Control statements File globs. Generate an output file for each build configuration supported by the current CMake Generator. For example, while CMake is running, it locates include files, libraries. Iâve commonly seen advice to avoid globbing for files because cmake wonât automatically rerun if a file is added. Actually, file(GENERATE) doesn't expand variables at all.Äocumentation for that command tells nothing about variable's expansion ![]()
