CMake項目

-1

我正在開發一個C++應用程序，使用我以前開發的庫。我不希望將二進制文件鏈接到我的新項目，因爲誰使用另一個plataform需要重建。所以，我想把這個另一個項目的cmake文件附加到這個新的項目中，當我編譯的時候，也建立這個庫。有人知道我是如何做到這一點的？非常感謝。

我的新CMake的文件：CMake項目

cmake_minimum_required(VERSION 3.4) 
project(DataBase) 

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 

set(SOURCE_FILES main.cpp DataBase.cpp DataBase.h String.h libString.a) 
add_executable(DataBase ${SOURCE_FILES})

編輯01：

現在我可以用這個CMake的編譯：

cmake_minimum_required(VERSION 3.4) 
project(String) 

include_directories(./include/cryptopp563/) 
#link_directories(./include/cryptopp563/) 
add_subdirectory(./include/cryptopp563/) 

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 

find_library(cryptopp include/cryptopp563/) 


set(SOURCE_FILES main.cpp String.cpp String.h RsaString.cpp RsaString.h) 

add_library(RsaString STATIC RsaString.cpp) 
add_library(String STATIC String.cpp) 

#add_executable(Teste ${SOURCE_FILES})

但是，如果我用德add_executable我收到此錯誤：

[ 2%] Built target RsaString
