Question

我正在处理这个project，这是一个相关的issue 我用Espeak TTs引擎取代了TTS flite引擎，所以我不得不修改CmakeLists.txt

find_package(Espeak REQUIRED)
include_directories(${Espeak_INCLUDE_DIRS})
set(LIBS ${LIBS} ${Espeak_LIBRARIES})
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR} /cmake/Modules/")
if (NOT Espeak_Found)
    message(FATAL_ERROR "Package Espeak required, but not found!")
endif(NOT Espeak_Found)

因为默认情况下不支持FindEspeak.cmake所以我将文件添加到cmake默认模块路径，编译项目并获得以下错误

我该怎么办？

我刚编辑了Espeak参数

 ############ Find ESPEAK TTS ############ 

find_path(LIBESPEAK_INCLUDE_DIRS 
          NAMES speak_lib.h
          HINTS /usr/include/espeak)
find_library(LIBESPEAK_LIBRARIES
             NAMES espeak
             HINTS /usr/lib/ /usr/x86_64-linux-gnu/
             PATH_SUFFIXES lib)

使用cmake对espeak的未定义引用
