如何将开源库包含到 C++ 项目中？

Question

I am trying to use an open-source library into my project, specifically this one here .

I have followed the installation guidelines and installed it globally with

sudo cmake --build "build" --config Release --target install

And I could see that the library is installed in /usr/local/lib , now back to my own C++ code, when I tried to

#include <benchmark/benchmark.h>

as shown in the instruction still no go with error

'benchmark/benchmark.h' file not found

SO is there any step that is missing?

In /usr/local/lib I have:

libbenchmark.a
libbenchmark_main.a

And in /usr/local/include I have:

benchmark

I am not using CMake for my XCode project.

-------------- Segmentation ------------

After digging on the question here.

I added this /usr/local/include into the Header Search Paths as following.

And then I tried

#include "benchmark/benchmark.h" // I tried <benchmark/benchmark.h> as well

But this resulted in a direct build failure with error

Undefined symbols for architecture x86_64:
  "benchmark::internal::InitializeStreams()", referenced from:
      ___cxx_global_var_init in main.o
ld: symbol(s) not found for architecture x86_64

Thanks for the many helps, I have finally figured it out.

Go to build settings in Xcode and add both header and library search path

And then go to linking , add linkers, for my case it looks like this

Assuming your project uses cmake too, your CMakeLists.txt should contain something like this:

find_package(benchmark REQUIRED)

add_executable(YouLibBenchamrkTarget sources1.cpp ...)
target_link_libraries(YouLibBenchamrkTarget YourLibraryTarget benchmark::benchmark)

This should resolve problems with include and linking issues (you didn't specified actual nature of your problem).
