I'm trying to use a library in my C ++ project with CMAKE, the problem that the library is loading the System class, not my class that has same name only the namespace that changes. It is as follows:
-ROOT
main.cpp
DataBase.cpp
DataBase.h // Este está com o #include "String.h"
includes
String
includes
String.h
RsaString.h
lib
libString.a
libRsaString.a
mysql
includes
windows
linux
macos
sqlite
CMakeList.txt
My CMake file looks like this:
cmake_minimum_required(VERSION 3.4)
project(DataBase)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")
include_directories(include/mysql/includes)
include_directories(include/sqlite)
include_directories(include/String/includes)
set(SOURCE_FILES main.cpp DataBase.cpp DataBase.h)
add_executable(DataBase ${SOURCE_FILES})
IF (WIN32)
#WINDOWS
target_link_libraries(DataBase ${CMAKE_SOURCE_DIR}/include/Mysql/windows/mysqlcppconn-static.lib)
ELSE()
IF(APPLE)
#MAC OS
target_link_libraries(DataBase ${CMAKE_SOURCE_DIR}/include/String/lib/libString.a)
target_link_libraries(DataBase ${CMAKE_SOURCE_DIR}/include/Mysql/macos/libmysqlcppconn-static.a)
ELSE()
#LINUX
target_link_libraries(DataBase ${CMAKE_SOURCE_DIR}/include/Mysql/linux/libmysqlcppconn-static.a)
ENDIF()
ENDIF()
Issue 1

But if I besides comment the line and put the complete PATH in the class include it compiles perfectly.

My problem is that I do not think it's good to practice for the full path in the library's include, correct? What would be the best way to solve this? For what I read on the internet, the correct thing is to use 'include_directories' but it generates an error.
