CMake，编译过程中不打印目录 [英] CMake , don't print directory when compiling process

问题描述

我最近将项目更新为CMake，有一件事令人讨厌。构建源文件时，它会打印保存目标文件的目录。

I recently updated my project to CMake, one thing is annoying. When building source files it prints the directory where object files are saved.

[ 13%] Building CXX object a/CMakeFiles/a.dir/src/A.cpp.o
[ 14%] Building CXX object b/CMakeFiles/b.dir/src/B.cpp.o
[ 15%] Building CXX object c/CMakeFiles/c.dir/src/C.cpp.o

我想这样

[ 13%] Building CXX object A.cpp.o
[ 14%] Building CXX object B.cpp.o
[ 15%] Building CXX object C.cpp.o

我找不到

推荐答案

作为 @ Hugues Moreau评论了这些文本直接编码到CMake中，无法修改。

As @Hugues Moreau commented those texts are directly coded into CMake and can't be modified.

您可以-无需利用其他脚本来解析命令行或输出-
仅通过设置global RULE_MESSAGES 属性设置为 OFF 并添加您自己的 echo 呼叫。

You could - without utilizing another script parsing your command line or output - only suppress the output with setting global RULE_MESSAGES property to OFF and adding your own echo call.

注意：

1. 它也省略了百分比和颜色信息


2. 仅适用于 Makefiles 生成器

1. It omits the percentage and color information also
2. It works only for Makefiles generators

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)

project(HelloWorld)

if(CMAKE_GENERATOR MATCHES "Makefiles")
    set_property(GLOBAL PROPERTY RULE_MESSAGES OFF)
    set(
        CMAKE_CXX_COMPILE_OBJECT 
        "$(CMAKE_COMMAND) -E echo Building <LANGUAGE> object $(@F)" 
        "${CMAKE_CXX_COMPILE_OBJECT}"
    )
endif()    

add_executable(HelloWorld main.cpp)
