cmake

问题 I have a small project with cmake. I build a lib and an executable. on the development machine I want also an executable that cannot be build on other machines/environments. e.g.: <my-lib> | -- CMakeLists.txt | + -- src/ -> build the lib/archive | |-- lib.c | |-- lib.h | |-- CMakeLists.txt | + -- tool -> build the tool | |-- tool.c | |-- CMakeLists.txt | + -- tests -> build the unit tests | |-- tests.c | |-- CMakeLists.txt I added CMakeLists.txt to all directories. Also an add_executable to

问题 Trying to use the AddressSanitizer tool (ASan) on my C++ project, I get a very verbose output full of undefined reference to '__asan_report_store8' and undefined reference to '__asan_report_load8' , and others like __asan_stack_malloc_2 . My project is built with CMake, and I've added the following line to my CMakeLists.txt: add_definitions(-fsanitize=address -g3 -fno-omit-frame-pointer) following these ASan examples: Example with makefile Jason Turner quick intro video Running the above

问题 I'm trying to compile a project using hwloc with CMake. However, I get a ton of undefined reference errors when linking: undefined reference to `hwloc_get_type_depth' undefined reference to `hwloc_bitmap_zero' [...] According to this answer to a similar question the order of flags is important. So, how can I generate a command like this in CMake? : g++ -Wall -std=c++11 source.cpp -lhwloc Excerpt from my CMakeLists.txt: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -std=c++11 -lhwloc") set

问题 I have a module project using cmake with the following configuration: cmake_minimum_required(VERSION 3.13) project(app) set(CMAKE_CXX_STANDARD 11) add_library(app MODULE src/library.cpp src/library.h) Once solution generated using cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release , I can find an app.sln solution. I open it with Visual Studio 2019 and click on the button Local Windows Debugger . I can see also a drop-down menu containing the value x64 and an item

问题 I want to do do something like this execute_process( COMMAND bash -c "git --git-dir ${CMAKE_SOURCE_DIR}/.git ls-files" OUTPUT_VARIABLE TRACKED_FILES) add_custom_target(all_file_project SOURCES ${TRACKED_FILES}) And the command itself seems to work as expected but the generated variable "TRACKED_FILES" contains only one logical entry (one multi line string) rather than a list of files. Can I somehow turn a string containing multiple lines separated by a newline ("\n") into a list in CMake? 回答1
