ua_pubsub.h: No such file or directory

按照截图中激活选项UA_ENABLE_PUBSUB等，详见截图，并修改cmakeLists文件option(UA_ENABLE_PUBSUB_MQTT "Enable publish/subscribe with mqtt (experimental)" ON)，off置位on；然后//cmake .. //make //sudo make install；成功后编译example中tutorial_pubsub_mqtt_publish.c文件，结果见运行结果及报错内容。

激活cmake选项UA_ENABLE_amalgamation,删除原build文件夹，重新编译；编译成功后将tutorial_pubsub_mqtt_publish.c文件中头文件引用改为“open62541.h",详细如下：
include "open62541.h"

include

编译gcc -std=c99 open62541.c tutorial_pubsub_mqtt_publish.c -o myServer
出现如下报错：
见代码@爱就是恒久忍耐

编译通过，生成可执行文件。

勾选上UA_BUILD_EXAMPLES

ua_pubsub.h头文件到底在哪？
