How can I use the PocketSphinx library in my C++ project? - c++

Question

I'm trying to use the PocketSphinx speech to text library in my project as a Git submodule. So, I added the submodule to my dependency folder and I added the following code to my MakeFile:
add_subdirectory(dependencies/pocketsphinx)
But, when I'm building the project, I'm getting an error saying that:
[build] /home/aniket/code/restapi/dependencies/pocketsphinx/src/allphone_search.c:43:10: fatal error: pocketsphinx.h: No such file or directory
[build] 43 | #include <pocketsphinx.h>
[build] | ^~~~~~~~~~~~~~~~
[build] compilation terminated.
My guess is that CMAKE cannot find the header files; but, when I build PocketSphinx alone it works fine.
I'm also using the JsonCpp library, which compiles without any problem.
My CMAKE file is:
cmake_minimum_required(VERSION 3.2.0)
project(assistant)
add_executable(${PROJECT_NAME} src/main.cpp)
add_subdirectory(dependencies/jsonpp)
add_subdirectory(dependencies/pocketsphinx)
target_include_directories(${PROJECT_NAME} PUBLIC include PUBLIC
dependencies/jsonpp/include)
target_include_directories(${PROJECT_NAME} PRIVATE include
PRIVATE dependencies/jsonpp/include)
target_link_directories(${PROJECT_NAME} PRIVATE build/lib)
target_link_libraries(${PROJECT_NAME} PRIVATE jsoncpp curl)
Here's my directory structure:
