我想使用autotools設置一個項目。我將需要將可執行文件鏈接到GLFW，但我無法使其運行。Autotools沒有正確鏈接GLFW
configure.ac：
AC_INIT([Test], [0.1], [[email protected]])
AM_INIT_AUTOMAKE([-Wall -Werror foreign])
AC_PROG_CXX
AC_CONFIG_HEADERS([config.h])
AC_CONFIG_FILES([
Makefile
src/Makefile
])
AC_OUTPUT
PKG_CHECK_MODULES([glfw3],[glfw3])
Makefile.am：
SUBDIRS = src
的src/Makefile.am：
bin_PROGRAMS = testapp
testapp_SOURCES = main.cpp
testapp_CFLAGS = ${glfw3_CFLAGS}
testapp_LDADD = ${glfw3_LIBS}
當我運行./configure，一切順利剛精細。 glfw3被發現爲expexted。但是，當我嘗試使用make編譯代碼時，看起來可執行文件沒有正確鏈接。

我在做什麼錯？該代碼是從http://www.glfw.org/documentation.html
