How to link to <math.h> library using CMake?

Question

I included library in my source code. But I get compilation errors.

Error: 
**undefined reference to \'sqrt\'
**undefined referen         


        

Answer 1

I found answer. Cmakelists.txt file is like it:

cmake_minimum_required(VERSION 3.6)
project(project_name)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 ")

set(SOURCE_FILES main.c)
add_executable(project_name ${SOURCE_FILES})

And you must add this command, for <math.h> or any standard library is similar.

target_link_libraries(project_name PRIVATE m)

That's all.
