KDevelop4 : Setting up a project using cmake

I am using Kdevelop4, and would like to use a default CMake c++ project.

My plan is to partition my application into programs, several shared libraries, and I would like to have a separate project building unit tests (I am planing to use google test).

I have several questions :

开发者_JS百科
1. How to modify default cmake file in order to get a shared library, and not an executable file?
2. How to integrate google testing framework with cmake?

The default CMakeLists.txt produced by KDevelop4 looks something like this :

project(kdevbook)

add_executable(kdevbook main.cpp)

1) For shared library:

add_library(kdevbooklib SHARED source.cpp)

More info.

2) Link.

Update:

Root CMakeList.txt:

CMAKE_MINIMUM_REQUIRED(VERSION 2.6.0)

PROJECT(MyGreatProject)

SET(LIBRARY_OUTPUT_PATH ${MyGreatProject_BINARY_DIR}/bin CACHE PATH
  "Single output directory for building all libraries.")
SET(EXECUTABLE_OUTPUT_PATH ${MyGreatProject_BINARY_DIR}/bin CACHE PATH
  "Single output directory for building all executables.")
MARK_AS_ADVANCED(LIBRARY_OUTPUT_PATH EXECUTABLE_OUTPUT_PATH)

ADD_SUBDIRECTORY(MyGreatProjectLib)
ADD_SUBDIRECTORY(MyGreatProjectBin)

Libs MyGreatProjectLib/CMakeLists.txt:

PROJECT(MyGreatProjectLib)

INCLUDE_DIRECTORIES(
  ${CMAKE_CURRENT_BINARY_DIR}
  ${CMAKE_CURRENT_SOURCE_DIR})

add_library(MyGreatProjectLib SHARED source.cpp)

Bin MyGreatProjectBin/CMakeLists.txt

PROJECT(MyGreatProjectBin)

INCLUDE_DIRECTORIES(
  ${CMAKE_CURRENT_BINARY_DIR}
  ${CMAKE_CURRENT_SOURCE_DIR}
  ${MyGreatProjectLib_SOURCE_DIR})

add_executable(MyGreatProjectBin main.cpp)

target_link_libraries(MyGreatProjectBin MyGreatProjectLib)
