[英]In CMake, specify all executables target_link_libraries certain libraries
In CMake, is there a way to specify that all my executables links to some library? 在CMake中,有没有办法指定我的所有可执行文件都链接到某个库? Basically I want all my executables link to tcmalloc and profiler.
基本上我希望我的所有可执行文件都链接到tcmalloc和profiler。 Simply specify -ltcmalloc and -lprofiler is not a good solution because I want to let CMake find the paths to the library in a portable way.
简单地指定-ltcmalloc和-lprofiler不是一个好的解决方案,因为我想让CMake以可移植的方式找到库的路径。
You can override the built-in add_executable
function with your own which always adds the required link dependencies: 您可以使用自己的内置
add_executable
函数覆盖它,它总是添加所需的链接依赖项:
macro (add_executable _name)
# invoke built-in add_executable
_add_executable(${ARGV})
if (TARGET ${_name})
target_link_libraries(${_name} tcmalloc profiler)
endif()
endmacro()
You can write a function/macro in CMake that does the work for you. 你可以在CMake中编写一个函数/宏来为你工作。
function(setup name sources
add_executable(name sources)
target_link_library(name tcmalloc profiler)
endfunction(setup)
setup(foo foo.c)
setup(bar bar.c)
