I have downloaded linux software of cypress SDK EZ-USB FX3 Software Development Kit. Inside Cypress/cyusb_linux_1.0.5/src there's many .cpp file that I compile with make and that work perfectly. I wanted to do my own cpp project so I copy the code of one of those files and tried to compile it using CMakeLists.txt. I have the following structure:
project/
├── include/
│ └── cyusb.h
├── src/
│ └── libcyusb.cpp
├── CMakeLists.txt
└── main.cpp
When I do:
$apt list --installed | grep -i libusb
libusb-1.0-0/bionic,now 2:1.0.21-2 amd64 [installed,automatic]
libusb-1.0-0-dev/bionic,now 2:1.0.21-2 amd64 [installed]
However, following this I get no response doing pkg-config --libs libusb but I did find something with:
$pkg-config --libs libusb-1.0
-lusb-1.0
So I added it to my CMakeLists.txt and right now it looks like this:
cmake_minimum_required(VERSION 3.10)
project(project)
set(CMAKE_CXX_STANDARD 14)
SET(GCC_COVERAGE_LINK_FLAGS "-lusb-1.0")
SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${GCC_COVERAGE_LINK_FLAGS}")
file(GLOB SOURCES
include/*.h
src/*.cpp
main.cpp
)
add_executable(project ${SOURCES})
When I hit make I get:
