None of the required 'libusb-1.0' found

这个问题折磨了我一整天 

用指令：

pkg-config --libs libusb-1.0

Package libusb-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libusb-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libusb-1.0' found

echo $PKG_CONFIG_PATH

/usr/share/pkgconfig:/usr/lib/pkgconfig

把 .pc 文件copy到 pkgconfig 的 环境路径下就可以了

cat /usr/lib/pkgconfig/libusb-1.0.pc 
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: libusb-1.0
