how to include a C library to a project with CmakeList.txt
this is a sample solution for Unix (Linux, OS X) users , for those who have installed libusb (or nother) and don't find it included in the standard library
if you follow the logs of hombrew (or any other package manager), you will find the path that homebrew has chosen for the installation of the library on your Os
locate libusb | grep .so (linux)
for my part, he added the library in "/ usr / local / Cellar / libusb",
well there is surely a way to add the library on the GCC standard library, but here I will show you an example of a cmakeList.txt file that you can use for your project to includ it on the project at least
open a new project and this is what you need to put in your cmakelist.txt file
cmake_minimum_required(VERSION 3.15)
project(libusb)
set(CMAKE_CXX_STANDARD 14)
add_executable(libusb main.cpp)
INCLUDE_DIRECTORIES(/usr/local/Cellar/libusb/1.0.23/include)
LINK_DIRECTORIES(/usr/local/Cellar/libusb/1.0.23/lib)
file(GLOB LIBRARIES "/usr/local/Cellar/libusb/1.0.23/lib/*.dylib")
message("LIBRARIES = ${LIBRARIES}")
TARGET_LINK_LIBRARIES(libusb ${LIBRARIES})
restart your compilation and it should work
if you have an idea of how I could add it back to the library that my gcc uses, you can post the solution down, thank you
